Hard to picture a person sitting down playing with a truck as a threat to anyone. This cop needs to move to a different profession. We know he won't see any prison time because he's a cop and just shot a citizen, but the least that needs to happen is he needs to lose his job.
AGain, in case you missed it, I SAID that I wasn’t addressing this particular issue. A person sitting CAN present a threat, just as a person lying on the ground can still be a threat. Rodney King presented a threat as long as he resisted and refused to comply with lawful policy orders, whether on the ground or not.
The shoot in question certainly sounds like a gross error by this cop. But “unarmed” doesn’t mean anything, generally.
