Interesting study. If criminals are better trained to commit violence than the law enforcement officers sworn to protect the public, how much less are we, the average citizen, prepared to face a hardened criminal who's decided to make us a victim? It really drives home the point that if we are to be truly self-reliant, we should each be taking on the responsibility every day to train our asses off, to prepare for the eventuality that one day someone is going to approach us with a weapon in their hand and murder in their eyes. Even then, like the study talked about, once we're confronted by an attacker, we're already at a disadvantage, as they've already targeted us, scoped us out, and have initiated violence.
It reminds me of a somewhat embarrassing situation I got myself into a few years ago. I was in my Explorer, in a store parking lot, when I witnessed a guy running out of a gas station with a case of beer in each hand and then jump into the back seat of a car which then drove off. I guess I'd left my brain at home that day, because I got the notion that I should follow them, get their plate info and then go back to the store and give it to them. So, I followed them about half a mile, not too close, but matched their speed.
When I followed them around the corner, two guys got out and the car took off. One of them picked up a cinderblock off the ground and they walked toward the passenger side of my car, the other guy walked to the left of my car. I was rolling slowly, not wanting to run them over, and the guy with the cinderblock raised it over his head and tried to throw it through my windshield. Luckily it hit the frame between the windshield and the door, dented it and bounced off. But, as I was watching him do that, the guy on my driver side sucker punched me in the back of the head as I drove past.
I remember driving off real slowly, kind of in shock from the whole thing. I was trying to figure out if I should stop and go back and fight those dudes, or just go about my business. All I know is I felt like a total chump for letting those guys do that and get away with it. And then I felt like an idiot for following them in the first place. But, I definitely lost confidence in myself and in my martial arts training that day. I learned my lesson, not to get involved with stuff that doesn't already involve me, unless someone's life is in danger. I think my biggest problem that day, besides following a car in the commission of a crime, was that I was not prepared for violence. Those guys were ready at the drop of a hat to fuck me up and I wasn't ready for it.
Edit: I did manage to get their license plate number and go back to give it to the guy in the gas station, for what little it's worth.
