And is there not a lesson for US to learn from that BTK press conference? A bare press conference does not mean the guy's innocent.
I don't know if this guy is guilty or delusional. However, I think that those whose profession it is to pursue justice need to stick with doing just that, and forget the PR work. Since most questions can't be answered in these pressers, the better thing would be to issue a written statement of what can be disclosed and get back to the business of investigating the case at hand. They can give themselves a pat on the back after the guy is found guilty.
