Last time I checked, the First Amendment did not cover threats. Threatening to harm another person is considered assault and is illegal just about anywhere - probably even in Canada.

I didn't read her original post, but - whatever she said - someone took her seriously enough to report it. The Secret Service read it and took it seriously enough to at least do a breif investigation and ask a few questions.

I seriously doubt that anyone is going to file any actual charges against her.

Threatening someone - anyone - is a stupid thing to do, even as a joke. Threatening the President is idiotic.
