SWATting someone goes way beyond just a bad joke. When you call in the cops and they show up dressed for Falluja and armed to the teeth all it takes is one oopsie and the intended victim is dead. To add insult to injury, the cops still don't need to apologize.
The LAPD caught a SWATter. Turns out to be a juvie so no names. Probably no serious time either, but one can hope. In an earlier time he's just be stalking celebrities, now one can aspire to being a mass murderer by proxy. Ain't technology grand?
