You are expecting the police to reliably figure out who is an actual threat but are presenting no realistic method by which they can do so.
Dang. I'm trying not to get involved in this crap again.
Oh well.
Somebody bought Tamir Rice an extremely dangerous toy. Somebody made it even more dangerous by taping over the orange tip it came with. Somebody let him take it to the park.
The police didn't show up at that park on a whim. They came as a response to 911 calls reporting an armed man in the park. The cops didn't know what else was going on.
Everyone important agrees that the cop used poor judgment. But pretending that the cop executed Rice for being black is worse than ridiculous.
