Open carry – really, for jackasses.


Ralph says it best “No one likes a jackass.”  Save the open carry for in the field while hunting or hiking or at organized political demonstrations.  If you open carry in the grocery store, you aren’t helping the cause.  You are being an attention-seeking douche.

Mass killings and school shootings are contagious


We’ve always warned about “copycat shootings” after a large active killer event.  Here’s an analysis that shows our suspicions are correct.  There is a heightened chance for another mass shooting in the 13 day time period after a previous mass shooting event.  The only problem is that the research relied on databases from USA Today and The Brady Center for Handgun Violence.  Neither of these are unbiased sources.  The original study is reported HERE.



In the Opponent’s Shoes: Increasing the Behavioral Validity of Attackers’ Judgments in Counterterrorism Models


While I’m sharing academic studies, here are a couple more.  This first one looks at how terrorists choose their targets.  The second is about Comparing Death Rates from Mass Public Shootings and Mass Public Violence in the US and Europe.  Both are worthwhile reads.



Random Thoughts on The Buggerance Factor


Some deep thoughts about training from my friend Marcus Wynne:

How about letting people fuck up (safely) and solve their own problems, instead of hovering over them like a Jewish mother on meth? Have you ever noticed, on a firearms training line, how often instructors step in at the first sign of difficulty and solve the problem for the student?

What does that do to the student’s brain? What’s the (unconscious) message in that action?

What it does is train the student, while under stress, to look around for someone else to help them solve the problem, or to solve the problem for them.

What is the non-verbal message transmitted by those actions? “You aren’t capable of figuring this out by yourself; I’ll do it for you, and then next time maybe you’ll remember how I solved it….”


I firmly agree with Marcus’ suggestions.  In fact, I’ve found in most of my classes that I get better results when I let students figure out their own solutions.  In my close range handgun shooting and knife fighting classes, students work against resisting opponents.  I tell them the goals of the drill and some minimal guidance and then let the work out the solutions themselves.  When students have problems, we bring the issue up to the entire group and let the group create a solution.  It works much better than merely forcing students to blindly follow my “script.”


Not only is Marcus a brilliant tactician and thinker, he is also a talented fiction writer…and he gets the gun stuff right.  Check out his books on Amazon.com.
