The commentator is Craig Silverman and I first heard the envelope speculation from him last week, although I can't remember which day. It was before Friday when I first heard him pitch it. He adds it is shear speculation on his part based on his disbelief that any competent DA would arrest Karr based on nothing more than his Bangkok "confession" and the Tracey e-mails.
But then, this is Boulder. Most people don't understand how truly weird the place is.
Yeah I heard SIlverman, But since I'd already sent the idea to several TV personalities, I wondered which one shared the idea with him. OTOH he could be on this thread? Or he could have read my mind or gotten it telepathically! %^)
