I would like to propose that the United States Government, as well as law enforcement agencies put an end to such treasonous behavior, as exhibited by Ted Nugent.

We respect their right to not agree with our President, but making threats on our Commander in Chiefs life crosses a very scary line, especially due to the prominence of the person saying it.
Arresting and charging Ted Nugent would send a message to those who continually threaten our President, that while you do have Freedom of Speech, there are some things it DOES NOT cover.
