 Hi Sheepdogs, 
     I address you as Sheepdogs because I recognize your ability and willingness to 
protect the innocent.  As my pastor says, you have a duty to protect the innocent.  
You don't have to protect yourself.  That's up to you.  But you have a moral obligation 
to protect the innocent.  Even if they are not yet born.  Even if they are old, useless, 
and a burden to society.  Even if they are mentally retarded. 
     This blog is continuing education for my students, friends, and interested parties.

Jeff Cooper's Rules of Gun Safety  
     "If violent crime is to be curbed, it is only the intended victim who can do it.  
The felon does not fear the police, and he fears neither judge nor jury.  Therefore
what he must fear is his victim."  
-- Col. Jeff Cooper
"Why Shooters Should ALWAYS Wear Eye & Ear Protection" by W.H. "Chip" Gross
     "Guns and ammo are mechanical devices that can and do fail.  You must be prepared."  
     “The problem with soft plugs alone is that some people don’t use them correctly;
they don’t insert them deeply enough into the ear canal, so the plugs don’t stay in place.”
     [Roll and press the foam ear plug between your thumb and fingers until it is long and thin.  
Insert it into your ear.  It should slip in easily because it is so thin.  If it doesn't, go back to
rolling and pressing.  Once you have the ear plug inserted, hold it in place until it expands
completely.  You should feel congested.  You should not be able to easily pull the ear plug
out. -- Jon Low]

John Farnam's rules to keep you out of trouble:  
Don't go to stupid places.  
Don't do stupid things.  
Don't hang out with stupid people.  
Be in bed by 10 PM.  Your own bed.  
Don't look like a freak.  
Don't fail the attitude test.  
----- Mindset (figuring out the correct way to think) -----
     If you look at someone bigger, faster, and stronger and immediately think,
'I'm at a disadvantage,'  
I have news for you:  you are.  
But that's only because you just put yourself there for no reason.  
     The truth is that anyone can do debilitating violence to anyone else.  
Your size, your speed, your strength, your gender --
all the factors that untrained people think make the difference when it comes to violence --
all matter far less than your mindset and your intent.

"The Fear of Guns Is No Gift; Here's How to Return It"
by Wendy LaFever
     "Fear serves a valuable purpose in our lives, but phobias don't."  
     "If your fear of guns has prevented you from learning about them or considering keeping
one for emergencies, I implore you to give it one more shot before you decide.  We here at
the NRA are ready to help you, and we here at NRA Women are rooting for you."  
"Lena Miculek on Conquering Fear"
     "The fact is, bravery isn't the same as fearlessness.  Bravery is acknowledging fear,
accepting fear and facing it head-on.  Fearlessness is your goal, but bravery is the only
road to it."  
"The Problem with the Sheepdog Analogy" by Jo Deering
     "I have no interest in running around defending the sheep.  If they don’t want to take
responsibility for their own safety, that’s their decision.  I’m not one to put myself in harm’s
way to protect grown adults who have abdicated their responsibility to protect themselves.  
Every person is going to feel differently about this, but I’m not likely to insert myself into
situations that aren’t my business.  That’s not to say I would never intervene in a violent
situation, but in general, if I can get out instead of getting involved or using violence, I will.  
The sheep (the adults, anyway—vulnerable children, elderly, disabled, etc. are a different
story) can live [or die] with the consequences of their own choices."  
     "Whatever you call me, I’m not a warrior seeking the chance to protect strangers.  I don’t
even consider myself to be “walking the hero’s path” as Grossman said.  I guess I don’t care
what you call me—just don’t call me a wolf, a sheep or a sheepdog."

in order to fit a concealed carry handgun into your life."

     When I shot the Low Light match at the Glock Store in Nashville, TN, some of
the guys were using weapon mounted lights (WML) (which are necessary for long
guns, because you need both hands for holding the weapon).  Guess what they were
doing with their WMLs?  They were searching for targets.  This violates our Safety
Rule II.  
     "So what?  It's just a game."  
     It's a training scar.  A very dangerous scar.

is WRONG!  Because they will use the WML to search.

     Violence is smooth elegant effortless technique.  No strength needed.  At least
that's how it's been when I used it.  That's how the Marine Corps taught it.  
     I was sitting in a coffee shop with wooden tables and wooden benches.  A guy
came in, recognized me, and started moving toward me.  I did not want to get attacked
sitting on a bench with my back to a wall and table in front of me.  So I got up and
moved between the tables to meet him.  I put my arms up and pushed him away (feint).  
He grabbed my shirt and pulled me towards him, which was my intended purpose
(because he was much stronger and bigger than me).  Because I was also pulling him
toward me, we came together much faster than he expected.  I moved to my left, his right.  
Swung my right leg up and down catching his right ankle/heel with my right ankle/heel,
kicking his right leg out from under him.  Causing him to fall backwards, as I pushed
forward.  I had intended to smash his head against the concrete floor.  But, things
never go as planned.  His head hit the edge of a table and snapped his head forward,
breaking his neck.  
     Yes, with practice, it is that effortless.  It was one of the first techniques the
Drill Instructors taught us in recruit training.  Twenty years later, it was still in
long-term memory and worked just fine.  
-- Jon Low  
     Every month, I give a 4 hour lecture for students to get their Tennessee Concealed
Carry permit under the auspices of Concealed Coalition.  (The students don't need the
permit to carry in Tennessee as we have had "Constitutional Carry" since July 1st of
last year.  But it's good for reciprocity and other things.  There is also a higher level permit,
the Tennessee Enhanced Handgun Permit, that allows for open carry and carry in
more places.)  
     When we have deaf students, Concealed Coalition will pay for two American Sign
Language interpreters for the deaf students.  Which makes it much easier on me, as my
sign language skills are mediocre.  
     The deaf students are not very warm to the police, as their interactions generally
turn out badly.  The police are not trained, nor are they familiar with the deaf community.  
The police are slow to figure out that shouting instructions is the wrong thing to do.  
For those of you who have been in law enforcement, you know that there is never enough
budget or time for training.  Especially for training in such specialties as dealing with deaf
people.  So the police officer will often shoot the deaf person, because the deaf person is
refusing to obey lawful commands.  Because the deaf person cannot hear the lawful
     With the proliferation of law abiding citizens purchasing pistols for self-defense
and the proliferation of training, I expect to see many more police officers shot.  Police
must be careful, because deaf suspects make very sympathetic defendants.  They've got
their sign language interpreter in the courtroom.  They've got their family, friends, and
community in the gallery.  It's politically difficult for a prosecutor to prosecute a disabled
     "I didn't now he was a police officer.  He came up behind me without warning and
drove me to the ground.  So, I shot him.  Previous attacks on me and fellow members
of the deaf community informed my decision to defend myself with lethal force.  The
police officer should have identified himself to me.  His failure to do so is on him.  
His failure to be cognizant of my disability is on him.  I am not responsible for wearing
a sign on my back saying, 'Deaf Person'.  Because that would attract an attack from
nasty persons.  Which the police have consistently refused to protect me from."  
     I could go on, but you get the idea.  
     Claude Werner had asked if a conscious observer of an event (such as shooting
something) affects the event.  And my answer was that there are certain denominations
of the religion of physics that claim that a conscious observer does affect the outcome
of an experiment.  And depending on your interpretation of the model, may even be
required for a resultant quantum state to exist.  The tree falling in the forest makes no
sound, unless there is a conscious observer to hear it.  
     May I invite your attention to
"How Many States Of Matter Are There?" by PBS
where the narrator talks about Prof. Max Tegmark's proposal that consciousness is a
state of matter (in the sense of solid, liquid, gas, plasma, etc.) in the information
theoretic sense.  [See Jade's video cited below.]  
     We are not talking about whether or not a witness to the shooting will affect your
decision to shoot or not to shoot.  We are talking about whether or not the presence
of a witness (as opposed to a security camera) will affect whether or not your bullet
hits the intended target.  Yes, I know that I am talking about events at the macroscopic
level.  But, even macroscopic events are affected by the Heisenberg Uncertainty
     In my physics classes, I would ask my students, "Can you get bowling balls to
diffract when passing through a doorway?"  The answer is yes.  The bowling ball
just needs to be moving very slowly, which is physically possible.  
De Broglie wavelength = Plank's constant ÷ the momentum of the bowling ball
As long as the wavelength is equal to or longer than the width of the doorway, the
bowling balls will diffract.  (The bowling balls will not go straight through the door
way, even if they don't hit the doorway.  Rather, they will go off at some angle with
probability determined by the Schrodinger Wave Equation.)  
     "Wait a minute, Adjunct (sometime, part time) Professor Low, even at 0 Kelvin, 
the zero point energy of the bowling ball will be high enough to make the wave 
length of the bowling ball shorter than the width of the doorway."  
     This is of course a thought experiment, performed in deep space far away from any
mass.  Zero point energy (vibrations of the bowling ball or heat of the bowling ball,
induced by the Heisenberg Uncertainty Principle) does not affect the translational
momentum of the bowling ball.  If you were to do a statistical mechanics analysis you
would find that the zero point energy (or any other perturbation) would cancel out.  
     "Why Pure Information Gives Off Heat" by Jade
Actually, there are reversible gates.  The XOR (exclusive or) operation is reversible in
the sense that if you perform an xor operation using bit sequence A and bit sequence B
resulting in bit sequence C,  A xor B = C, then it is now true that C xor B = A and that
C xor A = B.  So, the original bit sequences can be recovered, so the operation is reversible.  
(That's why XOR is so heavily used in cryptology.)  
     Of course, I may be wrong.  I haven't played with these concepts in several decades.

Excerpt from an email from Patrick Kilchermann --
Hello Responsibly Armed,
     I believe it was the University of Kansas professor John Senior who I first heard speak
of the differences between convergent solutions and divergent solutions.  
     Convergent solutions, he said, are those that - once solved - are solved universally.
His example was the bicycle.  To invent a bicycle (or lightbulb, or an umbrella) in one
place and at any time is to have invented them everywhere.  Improvements can be made,
but those too are universal.  
     Divergent solutions (on the other hand) are those solutions that are 'correct' only for a
certain person or culture or situation or scenario, or only at that particular time.  Educational
models, types of government, and utility clothing are good examples.  
     In the realm of 'concealed carry for the purpose of armed defense', if we are looking,
we can divide everything we discuss into these two categories.  
     Some things are objective realities, which we ourselves have to bend and conform to . . .
in our training, our gear selection, in our mindset development.  Such as the wisdom found
within the Combat Dynamics physical and psychological principles and models.  Or, what
pistol bullets are and aren't capable of.  The philosophies of self defense.  The governing
strategies for how fights avoided are won.  
     Other points within concealed carry are much more personal and subjective, and our
quest is an individual one, where we are looking for the things that work for us, personally,
right now.  Tactics are all divergent (that is how you'll avoid a confrontation with 'this' man
here on 'this' night; how you'll fight a particular 'field problem'.)  They are divergent because
every single scenario is made up of many unique and probably never-before-seen balances
of factors.  (This is why the WISE WARRIOR learns to THINK . . . not to memorize a
bunch of asininely mechanical one-size-fits-all-drills).  
     To be even more egg-heady about this I'll say:  This is why the art of concealed carry
proficiency, then, comes down to:  (1) Learning the governing principles, and then
(2) learning to dynamically implement them as fast as possible in tons of unique situations.  
These are two very different abilities!  Most people are naturally good at only one of these
two aspects . . . but we must push ourselves out of our comfort zone and get good at both!  
And we must become knowledgeable with #1 before we can effectively practice #2.
     Many of our personal gear selection choices require divergent solutions.  For this reason,
you've noticed that I don't spend a whole lot of time talking about specific pieces of gear.  
Anything I could offer would at best be a starting point; at worst a derailment or distraction.  
I'd rather educate on the bare minimum requirements of - say - a pistol, based on the
average demands of reality, and then let the individual user choose the pistol with the
preferred ergonomics and luxury features that fit within those constraints.

"What Do I Say After a Shooting?" by Greg Ellifritz
     High stress will induce diarrhea of the mouth and constipation of the brain.  
You will have false memories and temporary amnesia.  So, you will NOT tell the responding
officers things that actually happened because you don't remember them.  And you will
tell the responding officers things that did NOT happen because you have false memories.  
     You will not have seen obvious things that everyone else saw because you had tunnel
vision induced by high stress.  You will not hear things that everyone else heard because
you will have auditory exclusion induced by high stress.  
     If you shit and piss on yourself, don't hide it.  Tell the police officer, because it is physical
evidence that you feared for your life.  Which is different from having a subjectively reasonable
fear of death or serious bodily injury, or having an objectively reasonable fear of death or
grave bodily injury.  Now you have physical evidence.  Politely ask the officer to let you go
to change your clothes and to take a shower because you defecated and urinated on yourself.  
     Your initial emotion may be elation, survivor euphoria.  I'm alive!  I won!  
     You may feel regret.  I just took a human life.  
     You may feel self doubt.  If I had waited, I might not have had to shoot him.  
     You may feel fear and panic.  STOP!  Don't flee.  Don't tamper with evidence.  
Don't lie to the responding officers.  Just move yourself back into a state of regret
as best you can.  You're not going to lie to the officers, because you're not going
to talk to the officers.

"OOPS! When Bystanders are SHOT: The LEGAL Consequences!" by Andrew Branca
     Deep analysis.  
     Mens Rea:  (the state of mind, the intent)
1)  Accident, you didn't know there was a danger, you could not have known.  No liability.  
2)  Negligence, you should have known there was a danger.  Civil liability.  
(Self-defense is not a defense against negligence.)
3)  Reckless, you knew there was a danger, but you didn't care.  Criminal and civil liability.  
(Self-defense is not a defense against recklessness.)
4)  Intentional, you intended to kill him.  Criminal and civil liability.  
(Self-defense is a perfect defense against intentional homicide.  No criminal or civil liability.)  
     Good Samaritan laws don't apply.  
     Doctrine of "Transferred Intent".  
     Strict liability.  
"Kansas court:  Self defense does not apply when a bystander is hurt"
     Hat tip to Stephen P. Wenger, W2MRA.
     "A Kansas law allowing deadly force against an attacker doesn't protect people from
prosecution if a bystander is injured, the state's highest court declared Friday.  The Kansas
Supreme Court ruled in the case of a Wichita police officer whose shots at a charging dog
wounded a 9-year-old girl.  The justices ordered a trial in Sedgwick County District Court
for former Officer Dexter Betts on a felony reckless aggravated battery charge.  The December
2017 shooting happened after Betts and other officers responded to a call about domestic
violence and a suicide threat at a Wichita home.  Once inside, the dog charged at Betts, and
he fired twice.  His shots missed and hit the floor, and bullet fragments hit the girl above an
eye and on a toe, according to the court's decision.  Betts argued that he acted in self defense.  
A judge dismissed the case before trial, and the Kansas Court of Appeals upheld that decision.  
But Supreme Court Justice Dan Biles, writing for a unanimous state Supreme Court, said
Kansas law grants immunity from prosecution for force used specifically against an attacker
and doesn't mention bystanders.  Kansas Supreme Court rules that self-defense laws don't
apply when the bystander is injured.  "If the Legislature wishes to extend self-defense
immunity when an innocent bystander is hurt, it can do so," Biles wrote.  "In the meantime,
we find nothing in the statutes providing a blanket shield for reckless conduct injuring an
innocent bystander who was not reasonably perceived as an attacker."  
     The real problem of course is that Betts missed.  Lack of training and practice has dire
consequences.  A friend of ours from the Palmetto Gun Club fired 5 copper jacketed round
nose 45 ACP bullets into a dog that attacked him.  None of the bullets passed through the dog.  
They all remained in the dog.  So it's obvious to me that if Betts had hit what he was
aiming at there would have been no problem. -- Jon Low
     There are several problems with the reporting of this event, however.
     First, it appears the decision focused on the question of self-defense IMMUNITY,
not SELF-DEFENSE.  One might act in complete consistency with the law of self-defense,
but still have to make the case at court and not qualify for pre-trial immunity.  
     Second, the argument by the State is that the officer acted recklessly.  Conduct that is
reckless can never be lawful self-defense, by definition, because self-defense must be
reasonable, and recklessness is the absence of reasonableness.

Andrew F. Branca

     Your court appointed public defender is handling 100 to 200 other cases beside yours.  
You think he is going to spend any time with you?  How much time do you think
he is going to spend on your case?  That's why you have to hire your own attorney
and pay him in full up front.  After the case is resolved, the client has no incentive
to pay the attorney, and all attorney's know this.  So, if you don't have a million
dollars in a savings account, you better have a premium self-defense insurance policy.  
     There was a high profile murder case in Hawaii many decades ago.  Because of
the politics, the optics, the judge felt he had to appoint a politically powerful reputable
attorney, so the public, the activists, wouldn't complain about the defendant getting 
railroaded by the system.  So, the judge appointed my father, thinking that dad would 
make a good show of it and the riots would be avoided.  But dad's reputation was on 
the line, because it was a very high profile case.  
     The court has a fixed amount that they pay court appointed attorneys, which was
far below dad's normal fees.  But in Hawaii, when the court appoints a member of the
bar, the member cannot decline.  So dad was effectively taking the case pro bono,
including private investigators, expert witnesses, etc.  
     Courtroom battles are just like wars.  If you've got all your evidence and witnesses
lined up and your arguments are researched and backed with citations, you know you're
going to win.  And your intelligence and counter intelligence units should make sure
your enemy knows that you're going to win.  Because that controls the enemy's behavior.  
So over dinner at Oahu Country Club, dad told the prosecutor, "Do yourself a favor and
drop all charges, otherwise you're going to look like an idiot."  
That's the kind of attorney you want, not the overworked public defender.  
     Buy an insurance policy.  They are dirt cheap, because good guys rarely use them.  
"Law of Defense of Others: Defense of Family v. Strangers v. Active Shootings"
by Andrew Branca
     Only 11 states require all 5 elements of self-defense.  The other 39 states have no "Duty to
Retreat".  So the principle of avoidance is off the table.  The prosecutor can't claim that you
didn't have the privilege to use lethal force because you could have run away.  
     Reasonable person standard.  In just about all states.  
     Alter ego standard.  In South Carolina and maybe other states depending on how the trial
court interprets the case law.  
     Defense of strangers.  High legal risk.  High ambiguity.  
In a domestic, she will testify against you.  Sorry, that's just reality.  In some cases, the wife
and kids will show their appreciation for you stopping the man from beating them by
stabbing you with scissors, jumping you and scratching your eyes, etc.  What?  You thought
they were the Brady Bunch?  You're going to end up Macing all of them.  And they will all
testify that you were the initial aggressor.  
     Defense of people you know.  Low legal risk.  Low ambiguity.  
     Defense of strangers in an active murderer event.  Zero legal risk.  No ambiguity.

"Gun shop in residential area near governor's mansion does not need zoning permit,
city officials say" by Grace Altenhofen
Hat tip to Stephen P. Wenger, W2MRA
     Elizabeth and Travis Aslin of Des Moines appealed to the Des Moines Zoning Board of
Adjustment for a conditional use permit to allow their firearms business to operate out of their
home on Forest Drive.  The home, located across the street from Terrace Hill, the Iowa
governor's mansion, will be used for online firearm sales and on-premises customer pickups.  
A public hearing with the Zoning Board of Adjustment had been scheduled for Wednesday.  
Neighbors who signed a petition against the business's conditional use permit planned to
attend.  However, the hearing was removed from the agenda after Zoning Enforcement Officer
Erik Lundy announced Tuesday that the business does not need a zoning permit, and
"the proposed use is permitted in this zoning district."  A new law signed by
Gov. Kim Reynolds last month, codified in section 414.33 of the Code of Iowa, prevents cities
from prohibiting any "no-impact, home-based business" – home businesses that do not
exceed municipal occupancy limits or create parking issues.  The law also says a city may not
"otherwise require a person to apply, register, or obtain any permit, license, variance, or other
type of prior approval from the city to operate a no-impact home-based business."  Aslin's
business is protected under this law, according to Lundy's decision, and therefore does not
need a conditional use permit to operate.  A 2020 law signed by Gov. Reynolds also prohibits
cities from regulating the ownership and storage of firearms.

"Random Thoughts From CCW Qualification" by Mike Wood, Lieutenant Colonel (Ret.)
Hat tip to Stephen P. Wenger, W2MRA.  The following are Wenger's excerpt and comments.  
     " I [Mike Wood] attended a state-mandated refresher class to renew my CCW permit last
week, and had the opportunity to see about sixty “regular folks” (versus hardcore gun
enthusiasts, like us) complete a basic qualification test with their chosen gear . . . I had an
autopistol to shoot in addition to my revolver, so I shot that one first, and spent the rest of my
time helping other shooters load their mags, policing brass, and observing the festivities, as
I waited my turn to shoot my revolver, at the end.  Boy, did I get an eyeful . . . This qualification
event was quite remarkable, as I’ve never seen so many failures to fire in one setting.  It was
honestly, breathtakingly, shocking!  I must have seen three dozen failures to fire across the 60
shooters and 160+/- guns that attempted the course, and I probably didn’t even catch all of
them.  I’ve never seen so many malfunctions in a group of shooters before.  The course of fire
required shooters to load five rounds in their magazine for each of the ten strings of fire, and I
saw several shooters who were lucky to fire one or two of those five successfully, on some
strings, with the other three or four winding up on the ground.  It was hard, from my vantage
point, to determine the reason for all of these failures.  Most of them appeared to be
shooter-induced failures.  I saw a large number of slides that did not go into battery, and while
some of these stoppages may have resulted from equipment or maintenance issues, I’d be
willing to bet most of them were caused by a weak grip/platform, or by riding the slide when
the first round was chambered.  I also suspect that errant thumbs and fingers interfered with
the free travel of the slide in many cases, especially on the smaller guns.  A couple rounds
looked like they were jacked out when typically-ignored safety levers inadvertently worked
their way into the ON position, and deactivated the trigger, prompting the confused shooter to
cycle the slide in an attempt to remedy the problem.  I was actively policing the brass between
strings, and got the opportunity to inspect a lot of the unfired rounds that had been manually
ejected by the shooters as they attempted to fix their pistols.  There were a few duds in the mix,
that didn’t go off with a solid primer strike, and I actually witnessed a handful of these as they
happened, but they didn’t account for more than about 10% of the unfired rounds . . . About a
third of the rounds had light primer strikes, and these were probably the most concerning of all.  
These light strikes hinted at a mechanical problem with the gun, such as a broken firing
pin/striker, or a firing pin/striker that was “glued” in place by a buildup of excess solvents,
lubricants, and debris — a condition which is entirely avoidable, given proper maintenance
practices, but appears to be distressingly common, particularly in law enforcement circles,
where firearms maintenance doesn’t always get the attention it deserves.  It’s also possible
that the ammo could have been a problem (improper dimensions, resulting in too much
headspace, or a particularly robust primer), but again, my brief visual inspection of these
recovered rounds didn’t suggest it.  The ammo looked good, outside of the light primer
strikes . . . While I was policing all that brass, I found an ejector rod for some kind of revolver.  
The darned thing had unscrewed, and was just sitting there on the deck.  Oops.  Someone was
in for a bad surprise.  Hopefully they figured it out before the gun was placed back into service.  
It was a good reminder for all of us to check screws and ejector rods during our normal
maintenance and function checks.  Screws really do back out under recoil, and every
RevolverGuy should have a properly-fitting screwdriver in his cleaning kit . . . Alas, it turns out
that all was not well in revolver-land, either.  As we loaded our cylinders for the first string of
fire, I saw the shooter to my right point his gun at me, as he attempted to load the gun using
the most . . . creative, method I’d ever seen.  If you can imagine, this shooter had the gun lying
flat on its right side, with the grip pointing towards his belly and the barrel pointing to his left
(at me!).   He held the gun by pinching the top strap between the thumb and index finger of his
left hand, while his right hand tried to feed the chambers by sliding rounds into them from
right to left, parallel with the deck . . . After I pushed the gun away and told him to keep it
pointed downrange, he apologized and explained the obvious – that he didn’t have any
experience with the gun.  We took a time out and I showed him how to accomplish the task
safely and properly, and things went uneventfully after that.  It proved an important point,
though.  Revolver shooters are a minority these days, and well-trained revolver shooters are
even more scarce.  There was a time, in the not-too-distant past, when the revolver was the
baseline – the handgun everyone grew up with, the handgun that dominated the shooting
sports, the handgun that most institutional training programs were based upon – but that time
has passed.  It’s an autopistol world now, and the “institutional knowledge” of the revolver in
the greater “gun community” is at a low . . .
     Something that I've observed in a community with a lot of firearm enthusiasts is the many
spend big bucks on fancy pistols to shoot at the range but shop for “inexpensive” snubby
revolvers to carry on the street and spend very little time honing skill with them.  As Mike
suggests and I have stated repeatedly the “institutional knowledge” of us Revolversaurus rex
types is fading and those square-gunners who do own a revolver as some form of insurance
would do well to learn from us while we're still around.
-- Stephen P. Wenger, W2MRA
     If you have a thumb safety on your pistol that you press down to deactivate, you must
keep your thumb on top of the safety when shooting to ensure it stays down.  Otherwise,
something will bump it and the pistol won't work.  (model 1911's, Browning Hi Powers, etc.)
     If you have a thumb safety that deactivates by being pressed up, the design is WRONG!  
Get another pistol.  
-- Jon Low
     If the gun store clerk tells you that the trigger on your pistol cannot be moved to
accommodate the length of your trigger finger, he lies.  A competent gunsmith can move the
trigger.  Some gunsmiths won't do the job for fear of liability.  But some will.  
     "Some girls don't like guys like me.  Ah, but some girls do." -- Sawyer Brown
Moving the stock trigger may not be the best option.  You may need to replace the trigger
with an after market trigger.  That's fine.  
     Your grip must fit your firing side hand.  The tips of your middle finger and ring finger
must be able to point back towards you.  
     Your trigger must fit your trigger finger.  When the pistol is gripped correctly (barrel in line
with the bones in the forearm, web between the thumb and index finger up high and tight
against the tang, middle finger tight against the bottom of the trigger guard) and the slack is out
of the trigger, your trigger finger should be pressing the trigger straight to the rear.  No vector
component of lateral force.  
     You would never wear shoes or gloves that did not fit.  Why would you use a pistol that
doesn't fit your hand and trigger finger?  The life of your loved ones will depend on your
competence.  So get it right.

"Pistol Red Dots: What Happens When They Fail" by Dave Merrill
Hat tip to Stephen P. Wenger, W2MRA
     The article gives several suggestions for aiming the pistol when the red dot sight fails.  
     "Iain Harrison tells us he replaced Tasco PDP2s every couple thousand rounds, simply
because the early red dot sights couldn’t handle the recoil.  In the world of competitive
shooting, this is partially why larger custom frame-mounted, non-reciprocating dots gained
in popularity.  Physically mounting a red dot to a pistol slide is rough as hell on an optic.  
How rough?  10,000Gs with some setups.  That kind of force can make a whole helluva lot
fail, especially when an optic gets hammered for thousands of rounds . . . "  
     [The real problem with slide mounted red dot sights is that it changes the mass of the slide.  
That affects the reliability of the pistol.  Have you cut the slide to compensate for the extra
mass of the sight?  Have you changed the recoil spring to compensate for the change in mass
and mass distribution? -- Jon Low]  
     "Some day we’ll reach the point where slide-riding red dots will be as durable as their rifle
     [Red dot sights on rifles don't reciprocate.  So they are not getting banged back and forth
with every shot.  So the comparison is specious. -- Jon Low]
     "It’s not just dots dying either.  The window can become obscured from cracks, rain, an
accidental drop in the mud, or merely severe fogging from rapid environmental changes like
stepping out of an air-conditioned car into hot, muggy weather."  
     [If there are water droplets on your window, you will see many red dots.  If there is fog
on your window, you will see large star bursts. -- Jon Low]  
     [The window is a concave reflector that creates a virtual image.  The red dot is a virtual
image, not a real image.  This is a problem on many levels.  But, you'll need to take an
optics class at your local college physics department to understand why.  The problem
for combat purposes is that if the red dot sight gets knocked out of zero, you won't be able
to tell.  With iron sights, the sights will look wrong, pushed off to one side or the other.  But
with a red dot sight, the error in the sight could be microscopic and internal.  So you will
never notice it.  Until you hit the wrong guy.  But in combat, you might not notice that either.  
-- Jon Low]  
     If you live in an apartment where the maintenance guys (or others) have keys to your
apartment, you need to keep your guns (and other valuable stuff) locked up; in a closet,
in a foot locker, in a toolbox, etc.  Steel cable through the pipes under your sink might help.  
But not much if they are plastic.  A safe bolted into the floor or wall would be nice.  But who
can afford such?  Putting a lock on a closet door is pretty easy and cheap.

"The Association of Firearm Caliber With Likelihood of Death
From Gunshot Injury in Criminal Assaults"
by Anthony A. Braga, PhD and  Philip J. Cook, PhD
     Hat tip to Stephen P. Wenger, W2MRA.  
Bottom Line Up Front:  Shoot the largest caliber bullet that you can shoot accurately,
because it does make a difference statistically and in real world gunfights.  
     This is why I carry 45 ACP and recommend you do.  Accurate shooting is a matter of
technique, not strength.  Pistol recoil is very light compared to rifle or shotgun.  
     Stopping the attack requires penetration.  Because you must strike a vital organ in order to
stop the attack.  The heavier bullet will give you deeper penetration.  
     "But my bullet already has way more penetration than needed to pass through a human."  
     False!  Ballistic gelatin tests don't contain any bones.  Your bullets in combat will need to
penetrate bones, human arms and shoulders, heavy leather jackets, thick leather belts, sheet
steel car doors, car windshields, windows of buildings, etc.  
You need deep penetration.  That means +P ammo.  That mean 230 grain bullets.  
     You win gunfights with speed, power, and accuracy.  Speed and accuracy can be controlled
in real time during the gunfight.  Power is what you choose to carry.  It is fixed long before
the gunfight.

But, memories are not all we old farts have left.  As my pastor says,
"Why aren't you dead yet?  Because God has stuff for you to do.  So do it."  
     A college classmate called me and asked for help with a ransomware
attack on a friend's company.  I told him to ignore the attack and just
restore the data from back up.  He told me that the company did not
have any back up system.  I told him, that's the problem, not the
ransomware attack.  Eventually, the local disk drives would fail
(naturally, or by natural disaster, or by design) and they would have
the same problem.  My classmate told me that his friend who ran
the company told him that they could not afford to back up their data.  
I said that doesn't make sense, as memory is free (as taught in all
engineering schools when designing databases, storage systems, etc.).  
My classmate got back to me later saying that his friend told him that
they could not do remote back up because the data was sensitive
and the vendor could not guarantee data security in transit or at
the remote site.  I said that doesn't make sense, as they could encrypt
their data before back up.  
     And then I realized that I was talking to the risk mitigation guy
at the company (through my classmate, his friend, and others).  They
were trying to figure out what they were going to say to the insurance

     If you fear the bad guys will be able to decrypt your encrypted data using quantum
computers, you’re worrying about the wrong thing.  Cryptanalysis is hard.  (Persons who can
do it are rare.  Persons who can do it, who also have the hardware resources to do it are
extremely rare.)  Bribery, sexual seduction, extortion, blackmail, etc. are easy.  Social engineering is
very easy.

parking lot, I guarantee one of your employees will plug it into a computer on your network,
it will infect your network, and I’ll be in your network by this evening.  
     Scenario 2.  I investigate your employees and find one with a special interest.  I accidentally
bump into the employee and strike up a conversation (admiring her tattoos “Were those done
by Diego?”, “Your children are so well behaved, it says a lot about you.”, etc.)  We accidentally
discover our common interest in her special interest.  I tell her that I must share information
with her.  I ask her for a thumb drive to copy files onto, or I pull out a flash drive that I copy
files onto from my laptop computer and give it to her.  The information will be of high value.  
She will be delighted.  I will adjust my level of excitement to her level of excitement.  When
she sees her husband, she joyfully shares the information with him by plugging the drive into
his computer.  The next time he logs into his work computer from his personal laptop, I’m in.

with the sender as to purpose and authenticity.  Don’t open email attachments, until you

Bad passwords are not improved by being replaced by bad passwords.  So have your
employees create good passwords and leave them alone.  If you have a policy of changing
passwords on a periodic basis, you are cryptologically wrong.  And the enemy will take

them to record the password somewhere, which defeats the security of having passwords.  
Forcing the user to use certain characters restricts the space of passwords.  That means the
space is smaller and therefore easier to search.  If your policy forces your employees to use
particular characters, you are cryptologically wrong.  The enemy will take advantage of your

     Okay, Staff, so how do you create strong passwords?  Consider a string of numbers that has
significance to you and so is in your long-term memory.  The social security number of your
wife is not good.  Your wife is public knowledge.  Social security numbers are findable.  Your
mistress’ street number, birth date, measurements, and phone number would be a reasonable
string.  Hold down the shift key, type in the string, release the shift key.  That would be a
reasonable character sequence to embed in your password.  
Avoid words that appear in any dictionary in the world, including names of people, places, or
things.  Dictionary attacks are a thing.  Rather, consider poems, phrases, or clauses that you
know well.  “and in the darkness bind them.”  Which would compress to “aitdbt” or
“AITDBT” or “AiTdBt”, etc.  That would be a reasonable character sequence to concatenate
in your password.  
     I could go on, but you get the idea.  
     Communication security requires at least two things:  Something you know and something
you have.  
     The something you know could be your password, which can be changed if you allow it to
be compromised.  
     The something you have may be a pseudo-random number generator that is synchronized
with the generator running on the server.  Or it may be a number sent to your phone.  The
possibilities are limited by your imagination.  Your fingerprint or iris scan is not something you
have.  They cannot be changed.  Once they are compromised, you’re screwed forever.  If your
hands are cut up, covered with blood or dirt, the biometric readers won’t recognize your
     The next level after "something you know" and "something you have" would be the
"user’s ability to satisfy a zero-knowledge proof protocol" with the server.  You claim to be
Alice.  The server asks you a question based on the identity of Alice.  You respond.  Based on
the response and the profile of Alice, the server asks a question.  (Consider how the Israelis
interview persons at their airports.  Go deep, digging for more detail with each question.)  
You respond.  At worst, the protocol should be halving the probability of you not being Alice
with every correct response.  But the server does not end the game until a set number of
questions are answered (correctly or incorrectly).  If the server is satisfied, it grants access to
whichever accounts are appropriate.  If not, it grants access to a honey pot.  Pooh Bear loves
