Yeah, but thats the weird thing. Sarcasm is obvious, until it isn't. In 2013, is it reasonable to systematically ignore someone who says "i think imma shoot up a kindergarten?" I guess what I'm asking is what's the criteria you and I are using to determine he wasn't serious? I intuitively know he almost certainly wasn't going to act on that statement, but assuming I'm a law enforcement officer, how do I justify ignoring it?
The sarcasm was obvious from the comment alone, the sarcasm was doubly obvious when the statement is taken in the correct context, and the sarcasm is particularly obvious since the kid fucking said he was joking.
Discretion and basic human intelligence is a vital part of the system, and in that case it is not being used.
