The police is very nervous when doing that sort of thing, this is not normal stupid, this is not just like talking about a bomb in the waiting line at the airport...
Imagine if the police ended up beating up a member of the person's family they swatted? or shooting someone? or if there was an actual emergency they did not respond to because they were over there?
I say, let's charge him and be sure the news is spreading around so nobody thinks this is "funny".
Yes that sort of stupid deserves to be punished.
