Facebook threat's

These threat's should be taken seriously if the user fully means it. It should be because it's a threat! He only should be puninshed if he does what he says he's going to do. I say this because if he is just joking it's ok, and what if he is just joking? Then it's harmless. So if he does what he say's punish him then. One of my reason's is that he most likely doesn't mean it. Another is that he didn't do anything to blow the building up, so it's an empty threat.
