I'm sorry but this whole article is ridiculous. Yes, calling the police on someone for jokes is absolutely not okay, and he deserves punishment for it. But it seems very farfetched, and honestly pretty insane, that the police murdering an unarmed man is something you should consider happening when you call the police.
The police have the guns, they are responsible for using them. Whether the call is a hoax or not, the police should not kill anyone unless they absolutely have no other choice. If someone is unarmed this is obviously not the case.
It is ridiculous that this article tries to frame some idiot for murder / manslaughter. The police killed the guy. No one else.
