Brazilian Robbery Ends With Off Duties Taking Over

Watch the video and see how this shooting could have very easily gone much worse for the off-duty cops here.  If bad guy number two had any desire to kill the cops, he could have shot them both in the back of the head from a distance of less than 10 feet.  These cops got lucky.

For my cop friends, please don’t do stupid stuff like this.  How do you think this guy would have felt about confronting the criminals if the ensuing gunfight killed his wife?  It’s not worth it.   You aren’t getting paid to get into gunfights on your days off.  Let it go. “Not your people? Not your problem.”

Criminal Mindset – Make Yourself Harder to Kill

“Examine yourself with a criminal mindset throughout the day and see your vulnerabilities. Examine where you work, shop, and even where you get gas. Actively pay attention to your habits and try to correct them. Corrections are often just simple subtle shifts in behavior, however they must be consciously made to be effective.”

6 Great Shoulder Stretches and Mobility Exercises

Tight shoulders?   Read this. 

For some additional exercise related content, you may also like The 10 Week Functional Power Building Program (Part 1). Overall, it looks like a very intense routine for people who want to gain strength and size.  I saw a couple workouts utilizing high rep Olympic lifts as cardio.  When done occasionally, it’s probably fine, but in general I save the Olympic lifts for strength and power generation and use other modalities (like kettlebells) for cardiovascular fitness.

What a Bullet Does Inside Your Body & How to Survive a Gunshot Wound

“According to the National Safety Council, your overall odds of dying from a firearms discharge this year are about one in 514,000. Pretty small chance, as most of the soft spots on your body (around 80 percent) are not fatal areas when it comes to being shot. According to statistics, you have a 95 percent chance of surviving if you get to the hospital with your heart still beating.”



The Gunfighter’s Dream

I haven’t had the gunfighter dream in years.  Unlike the author, I have never found that intensive training triggered my nightmares.  Instead, I realized that my dreams were triggered by a subconscious recognition that my training was inadequate.  I started going to the shooting range after every one of those dreams.  They slowed in frequency.  Now I train a couple times a week and I never have the nightmares described in the article.



Uncle Scotty Stories: 6″ Revolvers and Why I Stopped Carrying A Clamshell Holster

Planning for Predicted Post-Election Violence

I don’t follow the usual preparedness blogger recipe for content, which involves stoking fear and urging the purchase of weapons and cloistering from the rest of society.  I don’t find that to be a particularly good recipe for a functional society.  We need prepared people setting a good example, helping others and leading the way.  We need all citizens doing these things.

In the following post, I will distill my guidance further to help jump start your efforts.  My usual preamble for such discussions applies here:  I offer my guidance to anyone who wishes to help build a better prepared community, irrespective of their political leanings and candidates of choice.  I urge every American of all backgrounds to better prepare themselves not just for post-election challenges but for the various perils we face year round.”

This is probably the most succinct summary of the case that I have seen. Mas describes why the cops were not indicted and brings up another issue. The woman’s boyfriend shot a cop during the raid. He was not indicted for that shooting for the exact reason the cops were no-billed.
