The Blue Brief: How To Survive a Carjacking

Cars are becoming increasingly difficult to hot wire.  We’ve become increasingly distracted by our phones.  Criminals are figuring out that if they want a car, it’s easier just to carjack you than it is to get any other way.  This article gives a lot of sound information about preventing that.




Nick Hughes dishes out some common sense advice.  Read his followup post on TSA Stupidity as well.



Don’t Be A Tactical Hobo

I personally embrace the concept of looking like a bum.  I’m retired.  I have no one I need to impress.  My mental energy is better used creating useful content and improving my knowledge and skills than it is trying to match my pocket square to my tie.  With that said, I know some of you like to look good.  This article/video covers that topic very well.

Dud Lessons

Ammo quality control continues to suffer.  I’ve seen quite a few dud rounds in this year’s classes.



The Cult of the EDC Concealment Pistol Weaponlight

For what it’s worth, I carried a WML for most of my career as a cop.  I have one on the gun I keep on my bedside table.  I do not carry a WML for CCW.  I agree with the author that not everyone needs a light on his gun.  I disagree with his assertion that if the light isn’t the brightest on the market, it’s virtually worthless.  If I can identify my target and the threat it provides, I’d say the light is bright enough.  A pitch black night in a rural field calls for different equipment than a well-lit grocery store parking lot.



Miniaturized Red Dot Systems for Duty Handgun Use

The post above covered WMLs.  What about red dot sights?  Here is the most recent edition of Aaron Cowan’s analysis.



Murder rates soar dramatically in cities after BLM protests

Very interesting data. In cities with large BLM protests, police shootings drop, but murder rates increase. The study doesn’t attempt to imply causality, but my guess is that both are caused by large scale “de-policing” in areas where protests are high profile. 
Cops got the message. You don’t want them to enforce laws, they won’t enforce laws. That means fewer people get killed in police custody, but it also means no one is arresting the murderers. 
I would say that this is a case of “unintended consequences” but I have a sneaking suspicion that everything occurring was completely intended.

Training Review–Greg Ellifritz’ Active Response Training/Extreme Close-Quarters Gunfighting

Last weekend I had a wonderful time teaching at Ed Monk’s Last Resort Range in Arkansas. Saturday was a sold out 18-person Close Quarters Gunfighting class. On Sunday, I taught a tactical medicine class to 14 more students.
One of the highlights of my weekend was meeting the Mountain Guerrilla in person. I was honored that he and a couple of his training crew attended my gunfighting class.
I appreciate the time he took to write up the very thorough review of the course linked above.

“The practical applications portions of the class were stellar. Without taking anything at all away from Paul and Cecil and others, this is honestly, probably the best ECQ gunfighting course, for the general gun owner, who is not interested in learning jiujitsu/MMA, that I’ve EVER taken, in 30+ years of training. It doesn’t have the intensity that Paul or Cecil’s classes do, nor the physical demands, but it is, in many ways, a lot more approachable for the layman, with no combat sports experience, than their work is. If you’re an experienced combat sports athlete, the physical portions will seem ridiculously simplistic, but if you’re NOT a combat sports athlete, it’ll teach you some effective, robust, resilient weapons to utilize if you find yourself in that situation, without a lot of regular practice.”
“Aside from the quality of the material and Greg’s pedagogical methods, one of my pet peeves in the training world is guys who take themselves too seriously. To be sure, the material should definitely be approached seriously, but the guy who puffs out his chest and insists on practicing his steely-eye dealer of death, “meat eater” war face, just annoys the shit out of me. As people who have trained with me can attest, I appreciate self-deprecating humor more than anything else. Greg is a friendly, approachable dude, who laughs a lot, and I don’t think I saw him, once during the entire day, without a smile on his face (and, to be honest, I don’t know that I’ve ever even seen a photograph of him without a smile on his face).”

Sherman shares some of Paul Gomez’ unpublished writing about the “Urban AK.”  Paul was an encyclopedia of knowledge about the AK.  I’m glad he was able to share it with me in an after hours AK shooting session following one of Craig Douglas’ ECQC classes back about 15 years ago.

Why You Should Be Rucking

Walking around with a weighted pack/vest is one of the best kinds of exercise to do.  When the weather cooperates, I try to ruck for several hours a week.  It’s my primary form of cardiovascular exercise these days.  While I have a weight vest capable of holding 50 pounds, I generally ruck with the 20 pound ZELUS Weighted Vest.  It’s about the same weight as my plate carrier with a couple rifle magazines but it doesn’t draw any attention when walking in public areas.  That particular vest is the most comfortable I’ve ever tried.
