MilkmanDan says... @greatgooglymoogly -- "Lethal force is only for when someone's life is actively being threatened." and @Mordhaus -- "You can't shoot a fleeing suspect in the back unless the officer has probable cause to believe the suspect 'poses a significant threat of death or serious bodily harm'." A fair investigation absolutely needs to happen. BUT, it is at least possible that it was reasonable for the officer to make the judgement call that the kid was an active and significant threat of death or bodily harm to other people. If he's running away from a car that was clearly used in a drive-by, with weapons in the car... I dunno, man. However questionable the officer's actions are, the kid getting himself into that situation requires a rather longer and even more questionable chain of life decisions. I'm not saying that stuff is known (I haven't read or watched anything beyond the video), and again a fair investigation into the officer's actions is absolutely necessary. But at some point, I think @transmorpher makes a solid counter argument -- again, IF the stuff about him clearly having just been involved with a drive-by is true. Live by the gun, expect to die by it.
