I think we really need some clarity in regard to "Officer Commands." It needs to be clear when police a requesting you do something and when they are giving you a legally binding order to do something. The problem is that they often give commands that are not legally binding, but they give them as if they are. So they need to absolutely stop doing that. If you are not legally required to do what they say they need to phrase it as such. If you ARE required to do what they say they need to phrase it as such.
I think the guy was acting erratically. Maybe he had a mental disorder or was dealing with some sort of other issue. I mean, he stops his SUV right in the middle of the road and runs away from it while it's still running and the doors are open. Someone said he said the car was going to blow up? Maybe he's just really dumb and thinks cars do like they do in the movies and sometimes just blow up. So maybe he had some weird engine noises or something and thought his car was about to explode so he was panicked? He put his hands up but he continued acting strange and went back to his SUV when he was being told to stop.
I'm not saying there was ever a moment when lethal force was justified. I don't even think the taser was justified (tasers can and have killed people). It's another example of cops being a little too twitchy with the trigger finger. Like everybody is just about to pull out a hidden weapon and kill them?
