A nice guy, but I'm still not sure if he was merely naive or a shill for a cover-up. He was so mealy mouthed and non-committal during the whole time he was a prosecutor I wondered whose side he was on. Either way, he gets a vote of no confidence from me.
Call me cynical, but I suspect that he uncovered stuff that was so ugly that it scared him out of taking it any further. Maybe the same black bag guys that killed Kathleen Willey's cat (and then caught her while jogging to ask about her children) "got to him", maybe he just figured that "this stuff is too ugly for The American People to handle, it's best left where it is, lest the fabric of society begin to unravel."
All I know is that somewhere along the line he started to -- as you said -- major in the minors, and it was obvious that he wasn't going to let anything major get any kind of traction. Somewhere along the line he seemed to change.
