@pzmyers Abuse of emergency services is already an indictable offence (aka felony) in most states is it not? The problem here is such charges are rarely placed against people whom participate in "SWATing"
A secondary problem here is this would not be the serious problem it is in the United States if the police didn't have to go in like the fucking military every time they receive a call like this. There is a principle in law enforcement training - at least the training I received a long time ago now mind - called 'proportionate response'. Which is to say you need to respond to a situation with the appropriate tools for the situation - and should be trying to de-escalate that whereever possible (as a matter of efficiency). Going in full Rambo style because of an anonymous phone type, is the exact opposite of a proportionate response.
