"Officers gave [the victim] several verbal commands to put his hands up and walk towards them. The male complied for a very short time and then put his hands back down to his waist. The officers continued to give him verbal commands to put his hands up, and he lowered them again." [1]
I'm not well informed on the subject, but wouldn't equipping tactical teams with non-lethal weapons have prevented tragedies like this? The moment a team feels uneasy, they should feel free to stun the suspect. I know electroshock weapons have their own risks, but surely they aren't greater than firing a dude acting suspiciously with a live round from a Colt AR-15?
