Well based on how many people I know who have interacted with police, and who have even been caught doing illegal things have all managed to stay alive, I would guess that running, attacking, or moving in a threatening manner plays a huge role in how things are viewed.
I already said that the officer should never have moved the taser. That was a stupid move on his part.
What I find funny is that you always defend the person who was shot. You don't wait to see what evidence is out there. You just hear "unarmed, shot by officer", and presume the officer was in the wrong.
Now that we've had days of reports that this guy was unarmed and just running away from the officer, we finally hear more info. Like the fact that this was a dead-beat loser who'd been arrested several times before, and who had yet another warrant out. This same guy fled from the officer first chance he got, and when the officer caught him the first time, he struggled and fought.
It makes a difference, and I don't give a damn if the guy was jay walking or had a body stuffed in the trunk of his car. If you act like a suspicious jackass, you're putting your life at risk.
Officers shouldn't have to try to discern whether fleeing means that a person has a minor violation, or whether they are the most evil dirt bag ever. If they attack an officer and then flee, then as far as I'm concerned, take them down. There's no way to know if they're armed. There's no way to tell if they won't attack a civilian in order to keep police at bay.
It's a hard line to draw, but I'm comfortable with that line. Better to be overly cautious and shoot someone who isn't armed than to allow them the chance to hurt someone else.
