>>>Gee what happened to the first amendment?
The First Amendment is not an absolute right. There have been limits placed on it. For example, laws against defamation, libel and slander; it is illegal to incite crowds to violence; obscenity can be regulated.
I'm sorry, but expressing the opinion that you like to kill the president should be a protected right.
A conspiracy to kill the president, or a threat followed by some action towards accomplishing that goal is and should be illegal.
But merely stating (in this case probably in reaction to something the president had just said) that you'd like to kill the bastard is a right that all Free Men should enjoy.
The first amendment protects our right to say stupid things. Expressing what is in our hearts, no matter how vile those thoughts might be, should NEVER be a crime. NEVER!
