All of the evidence is with the FBI, or probably by now, long since shredded, digital copies wiped (like with a cloth? cackles), and any hope of filing together REAL evidence is long gone. Hopefully, some FBI was dumb enough and cocky enough, to keep a copy for whatever egotistical reason he has, and the white hats have that, OR, they may have it all along, and they're waiting to release it. These are the options, I tend to believe the first is true :(

why would there be evidence? I'd love to have evidence of it but it really wouldn't be hard to prevent that especially in the days before everyone had a camera in their pocket.
