It actually is illegal to say that you are going to kill the president or that he should be killed. This guys in huge trouble.
About Viginia's seal. That dude is totally looking up her dress too. Dang!!!
All that will happen is the Secret Service will invsetigate him. If they believe he's going to comit an act against the presidents life they'll arrest him... if they don't... they won't do anything... unless someone else attempts something against Obama... and then they'll have to prove that the guy was motivated by this guy.
At least i'm pretty sure that's how it works.
There is definitely a law that doesn't allow you to say that you are going to take the president's life. That is one instance where American's don't have freedom of speech. I guess you could say that what this guy said wasn't a direct threat though so it could be open for interpretation.
There is a law where you can't say you are going to take the presidents life... but to convict someone you need to prove intent and that they really meant to threaten the Presidents life....
Which is practically impossible to prove unless they're actually planning something, or an act takes place. (And even in the second it's hard to prove.)
The secret service investigates something like 1,500 threats against the president a year. Almost none of them receive any punishment for said threats.
Any halfway decent lawyer can claim hyperbole or something similar.
Along the lines of "She borrowed my sweater without asking. I'm going to kill her!'
