When a Gun Is Not a Gun

19GRAYsub-articleLarge

Fascinating information about the science behind mistaken identity shootings.  From the article:

 

“In a dangerous, high-pressure situation such as a possible crime scene, it’s conceivable that some police shooters actually see a weapon when none is present. Other research from our lab (done by Professor Wormwood in collaboration with the psychologist David DeSteno) supports this possibility. In a set of five studies published in 2010 in the Journal of Personality and Social Psychology, we asked test subjects to identify whether individuals were holding guns or harmless objects like wallets and cellphones. Our subjects reported more weapons when they were feeling angry, regardless of what the individuals were actually holding.

Let us reiterate: We are not claiming that affective realism is the preferred explanation for police shootings that involve the misidentification of weapons. Nor are we claiming that racial bias has had nothing to do with such shootings. Indeed, affective realism may be one pernicious way in which racial bias expresses itself.

What we do know is that the brain is wired for prediction, and you predict most of the sights, sounds and other sensations in your life. You are, in large measure, the architect of your own experience.”

 

 

Decision made! The all-copper hollow point

 asst DPX recovered bullets

Dave Spaulding makes a case for carrying the all-copper hollowpoint bullet (like the CorBon DPX) as a defensive round.  My general advice is to look for a hollowpoint from a quality manufacturer that penetrates at least 12″ in ballistic gelatin and expands to at least 1,5x its original diameter.  Taking a look at the accompanying chart, most of these rounds meet that criteria.  I think that this type of bullet will be where future ballistic innovations occur.

Decision-making in the Kimball shooting

ruger-lcp

The outcome of this case may surprise all of you folks who are in the “I’d just shoot him” camp.  The jury ignored a significant disparity of force issue when a man shot another person (who was 6″ taller and 100 pounds heavier) during a physical assault.  Guns aren’t the only answer.  You better have some physical skills and/or a less lethal weapon as well if you want to stay out of prison.  Claude discusses the basic facts of the shooting HERE.

Federal HST 9mm and 380 Auto Comparison Tests

canvas

It’s no secret that I’m a fan of the Federal HST loads for defensive use.  Federal just came out with a .380 version of the HST hollowpoint.  This article tests the load in comparison with  one of the 9mm HST loadings.  The authors don’t seem to be too happy with the .380 performance, but it doesn’t seem significantly worse than other .380 rounds on the market.  The .380 is a marginal caliber.  You just can’t do everything with that round.  If you want penetration, you don’t get expansion.  If you want expansion, the round only penetrates about 10″.  That’s the way it works with this caliber.
