I remember watching that on CNN the morning of the bombing, John Doe #2 was all over the airwaves. And by that afternoon, he was gone as if he never existed. Neither the gubmint nor the news pukes wanted to talk about him any more. Seemed real strange to me. The conspiracy theories always seem to write themselves.
Some early news reports mentioned that suspected bomber(s) may be Middle Eastern and that went away quickly as well. At least to my recollection. I can’t remember it clearly now, not sure if that was speculation or from an eye witness report...
