Anyone remember Gary Condit? He was that Congressman that everyone was convinced was guilty of murdering a woman named Chandra Levy. Lots of people cared passionately about finding Ms. Levy's killer, back when they thought it was probably him — this, despite the fact that no one in law enforcement ever thought Condit was a suspect. Since her body was found and the evidence never quite managed to point to the sleazy politician, everyone lost interest in her.
Condit is forgotten but not gone: He's presently suing writer Dominick Dunne over some rather wild, factless accusations in a case that tests our concept of the First Amendment and what it should and shouldn't protect. John W. Dean has an article about it which you can read by clicking here.
