I'm not getting into this racism mess of a political debate. I just wanted to clarify some points.
As far as where you aim the gun.. not everyone issued a gun is much above a marksman. If you're aiming to shoot someone At All, the idea is imminent danger is there and present on your life. In which case, deadly force is authorized. And since its authorized, you shoot center mass. If you're Rambo/John Wayne and you've been six-shootin' your whole life, sure, aim for the shoulders. If you're cool as a cucumber under pressure, and being scared for your life and safety doesn't mess up your aim, I see no problem with it, and there are certainly situations where those people are there. Most people would not be able to though. It's a small, moving target, in comparison to center mass.
The biggest problem with aiming for shoulders is that there's a field of shot groups you shoot at.. Aiming at the shoulders puts the head in that group. You jerk that trigger just slightly wrong, and there goes the head-- practically no chance of survival versus some.
Tasers only work so far as well. That was a pretty damn huge guy... anyone on adrenaline, huge, used to it, etc. etc. It's not guaranteed to work. I wish it were--I think many police officers would carry ONLY tasers if they had the range, accuracy, and subduing power that people think they magically do. Alas, they don't. It works in some situations, but not others at all. As big as that guy was, and with a knife, I wouldn't have gambled my life on a taser working before he got to me. It isn't a miracle weapon. It's a good one, but it won't work in all situations at all, and sometimes not even when it is a good situation for one. That isn't even counting the tenacity someone can have while on drugs.. things that would kill most people don't even affect those doped up on some drugs. And you never know--when people make stupid decisions like robbing a place and running at police, the suspicion of drug use is up there. There are plenty of stories of people running straight through bullets.. a taser wouldn't do much good in situations like that.
Just trying to give some perspectives to everyone always thinking tasers and stuff were magic weapons. If they worked as great as people say they did, it'd be all common cops carry because they're cheaper than real guns.
In general, outside of this? More than you'd think. People don't know the ins and outs of everything, but they know enough to formulate opinions, and it all goes downhill from there.And who actually expects the police to do this?
