We know that it may be wishful thinking, but we'd like to think that the people who produce TV news shows feel some moral obligation to civility or responsible debate that transcends -- at least once in a great while -- their desire for a controversial guest. If we're right about that, then maybe, just maybe, we've seen the last of Ann Coulter on network TV.

Coulter was last in the news for claiming that the 9/11 widows who oppose the policies of George W. Bush are guilty of "enjoying" their husbands' deaths. This time around? In an e-mail exchange with the editor of a conservative site, Coulter seems to be advocating the murder of Democratic Rep. Jack Murtha.

As Editor and Publisher reports, Coulter was asked to do the name-association thing with several prominent Democrats. When she got to Murtha, Coulter wrote: "The reason soldiers invented 'fragging.'"

"Fragging," as Editor and Publisher notes, is the Vietnam-era term to describe the killing of an officer by one of his own soldiers.
