The cops found two people [1] to say that it was okay to kill a 12 year old boy carrying a toy gun at a park in a state with legal open carry, two seconds after arriving on the scene. If you think that’s okay, maybe you shouldn’t be a cop.
It’s not okay.
It might be legal. It might be within policies. If so, it means the law, and the policies, are wrong.
