What fracken caliber is he using to shoot him at very close range w/o tearing him up?
Maybe the guy was issued a pellet gun, because of how trigger-happy he was, sort of like Barney Fife (except Barney always had a gun with no bullets, IIRC).
I think there is definitely a racial component, for sure. If I get pulled over, and the officer asks me for my license/registration, I'm probably going to ask him if I can reach into the glove compartment to get the registration. I'm certainly not going to make any sudden quick movements, towards the back seat, etc. And, if I'm standing outside of the car, I'm certainly not going to reach quickly into the car, no matter what they've asked me to do. On top of all of that, if I was black, multiply all of that times 10. In other words, I'd be extra damn sure that I don't do anything to give them any cause for alarm. So, in other words, it probably wasn't in the guy's best interest to move as quickly as he did (whether he wanted to win the "shot in the leg" lottery or not).
That said, what he did (reaching quickly into his vehicle) certainly does not justify being shot (in the back, no less). Not to mention, as others have said, the cop didn't stop shooting until well after the situation was under control (at least in terms of the other guy clearly being of no harm to him). And shooting in a gas station parking lot, with people all over the place? Are you kidding me?
I mentioned this story to my wife yesterday, and we actually got into a pretty big argument over it. Her brother is a CHP sergeant in SoCal (not a trigger-happy type of guy, at all, in my opinion, by the way), and according to her, he would say that this shooting is justified (based on the cop feeling that he was at risk). Now, I don't think that my wife has actually talked to her brother about this particular incident (they have chatted about the one in Missouri, though), so I don't know for sure what he would say. From what she has told me, though (based on their conversations), times have changed. I was always under the impression that cops don't shoot people unless they see that the person in question has a weapon (or maybe not even unless the weapon is being pointed in the cop's direction). According to my BIL, that's not the case. If someone is being aggressive to the point where a cop feels threatened, they have the right to shoot to kill.
I do know that cops are put in life-threatening situations every day, and I understand people like my wife being worried (for her brother's safety). He has lost members of his department (to shootings), and was involved in a pretty serious accident this spring, as a result of a high-speed chase. So, I get that it's a dangerous job, and the situations are not always black and white (no pun intended). But, I have a hard time believing that it's OK (in any rational person's mind) to shoot someone in the back, particularly when there is no reason to believe that they are armed (after all, this was in relation to a potential seat belt violation, right?).
This seems like a classic case of how one (or a few) bad apple(s) ruin things for everyone else. The cop, in the sense that knuckleheads like him give cops (in general) a bad reputation. And, the victim, in the sense that he probably doesn't get shot if he isn't black. In other words, unfortunately, enough people in his situation HAVE pulled guns from their vehicles that every cop is going to at least have that potential scenario in the back of their mind. Most react and handle the situation appropriately. This cop clearly did not.
