Sure, I’d be upset if the slain person was close to me, but I am looking at the situation in light of established law in the USA. A cop in the course of his legal duties who makes a momentary mistake is not doing a criminal act when the mistake results in harm of another. The same law works for other professionals. Heart doctors used to goof hooking up the heart lung lines until the machine maker colored the line in red and the line out blue. Same deal with the same shape of the grip on a gun/Tazer, but these should have different shapes as one does not look when grabbing in haste.
Are we saying that cops are reaching to tase people so quickly they can’t even tell if they got a friggin taser in their hand? I sure as hell don’t reach for my weapons in “haste” unless I think injury to myself or my family is imminent.
On one hand I don't think the cop would deliberately pull a gun and shoot the man in the back, on the other hand I don't see how you can mistake a gun in your hand for a taser, even in the heat of the moment.
This man was on the ground with two other officers on top of him, there was no threat to any of them and the shooter over reacted. Remember, cops are supposed to be trained professionals (their own words) so they should be held to a higher standard and not make "mistakes"
When ordinary citizens who defend themselves are given the same considerations as cops when they defend themselves or their families, I'd be more willing to cut the guy some slack. And in this case, the cop was not even defending himself or others
At this point, I believe this is involuntary manslaughter, JMO
