Mental Health Reform Will Not Reduce US Gun Violence, Experts Say


But while few people would disagree with the need for mental health reform, scientists who study gun violence say it won’t make much of a dent in the number of homicides and attempted homicides committed with firearms. That’s because although mass shooters are likely to be mentally ill (but not necessarily diagnosed), high-profile mass shootings represent only a small fraction of US gun violence, the vast majority of which is committed by people who are not mentally ill. In addition, most people with mental illness are not violent; they are far more likely to be the victims than the perpetrators of shootings.



Interview with Paul Sharp

FireShot Screen Capture #092 - 'Interview with Paul Sharp (English) I alway_' - bringaknife_wordpress_com_2015_12_17_interview-with-paul-sharp-english

A very good interview with Paul Sharp of Sharp Defense.

“Slamming someone into the ground with as much speed and power as possible is far more damaging and dangerous to my opponent’s health then any esoteric eye jabbing type thing. “

You’ll also want to check out the same site’s interview with Ed Calderon.



How To NOT Get Shot by Responding Law Enforcement


Excellent advice here for avoiding being accidentally shot by police if you respond to an active killer attack.



The Best Bad Choice


“A tactical decision is only sound or unsound in light of the particular context in which it’s being made, and in comparison to the reasonable alternatives. So let’s not get all huffy calling other people’s decisions about being armed unsound. That decision may be the most reasonable one in their circumstances. Of course, it also may not be. There may have been better decisions they could’ve reasonably made. But constructive criticism should be made acknowledging — and in consideration of — their particular circumstances.”



Testing G2 R.I.P., Liberty Civil Defense, Inceptor, and Lehigh Defense Rounds – Part 2 – Bare Gel


The Firearms Blog conducts  thorough ballistic gelatin testing on four different “specialized” defensive rounds.  I am honestly more impressed with these rounds than I expected to be.  I still don’t have much use for them, but they performed better than I thought they would.

The RIP is probably the most curious of the four rounds.  It’s main section generally penetrated deep enough to meet FBI minimum standards.  Just keep in mind that a small portion of the bullet diameter reaching 12″ in gelatin will “pass” the test, but may not be ideal in the real world.  I can find .22 bullets that will penetrate 12″ of gel, but that doesn’t mean that they cause extensive tissue damage when doing so.

Bottom line for me is that the FBI wound ballistics experts thoroughly tested the RIP when it first came out.  They concluded that the round offered no advantages over their traditional jacketed hollowpoint issue load.  I’m going to stay with their recommendations.  You won’t see any of these loads in my defensive handguns.



Policing Isn’t That Dangerous?


A closer look at the workplace violence risks that police officers actually face.




A profoundly interesting look at the historical development of the military fighting knife. H/T to Practical Eschatology for finding the article.



Shivs and Shanks: Part Five


Weaponizing a three-ring binder. Learn to think like this and you will never be unarmed.



Violence happens.


Speaking of knives and improvised weapons, here’s a nice review of Ed’s Manifesto from my friends at Recoil Magazine.

“Really.. All you need is for it to have a point and a handle, and to have it in your hand when you need it. Anything else is just sprinkles on a cupcake… A very sharp deadly cupcake.”



Disgraceful Carry Permit Instructors

Quality advice from James Yeager.  Vet your instructors.  I have a link to my training resume right on my site.  You can see who I’ve trained with and what I’ve learned.  If your instructor has only a weekend NRA cert, they probably shouldn’t be teaching.



Merry Christmas, Bob


My favorite T-Nation article of all time. A little dose of holiday inspiration for all of you.



‘Run, Hide, Fight’ Is Not How Our Brains Work


Freezing in a dangerous situation is natural, but counterproductive.  We need to recognize those “freeze” moments and turn them into productive activity.  For some more info on the “freeze response.” check out this article from the CP Journal (the folks who wrote Left of Bang).



When Self-Defense is Outlawed, to Run Away is Your Only Defense

I’ve been critical of the “run, hide, fight” model, but the Brits have made it even worse by removing the “fight.”  Their active killer response is “run, hide, tell.”  For real.  I like weapons man’s preferred model of “arm, prepare, hunt.

With that said, this short British police video on active killer response actually shares some pretty good information and is worth watching.

    Thank you. Merry Christmas and happy new year! Hope to see more articles coming in 2016. Also, I think it might be useful if you can publish some statistics of the visit traffic of your web for 2015.

    • Greg Ellifritz says:

      Look for the “2015 Training Year in Review” post that I’ll be putting up in a couple weeks. I’ll talk about some of the web traffic details in it. What specifically are you interested in?

      • Armedasian says:

        Thanks for the reply. In addition to most popular articles and most insightful/ useful articles rated by you, I think it is nice to put some demographic information about my fellow readers: where does the traffic come from ( I saw other websites with map of the US covered with circles representing orgins of traffic and the size of circle is porpional to amount of traffic), when do people visit your site ( work time, early evening, or mid night?), is there any peak in traffic and to what event can the p aka be attributed ( Baltimore, ISIS, Paris?)
        Again, thank you and wish you a happy 2016.

    Also, regarding the last article in today’s dump, it is usually quite difficult to find crime statistics relate Asian and Native American populations. There is alway information regarding black, white, Hispanic, non-Hispanic, but somehow Asians become invisible in crime statistics.
