I won't deny that the evidence strongly suggests that Ritter is guilty as charged. But why does that mean he was not set up? If he was targeted because of his politics (and that seems possible to me,) "set up" strikes me as an accurate term.
If he is "anonymously" chatting, how does a blackmailer find which chat room Scott Ritter was going to?
Did he go back to the same one where he was busted before?
