it does look like the wedding story was incorrect in stating when he was fired. according to his bio, " he later joined the New England Patriots of the National Football League, where he served primarily as an Area Scout and Video Assistant from 1996-2003, being a part of two Super Bowl teams and winning a Super Bowl ring for Super Bowl XXXVI."

he probably does have some dirt, and he probably is sick of being a nobody. but he is right in being afraid of the "wrath of the pats" . i wouldnt like to be tied up in court forever either. the fact that he is afraid of being tied up in court however implies that his evidence is sketchy and would pose legal problems for him if he releases it. testimony is a different story however.
But the memo came out in 07 so this is a non-story!!
personally, i dont have much doubt that we stole signals back then. why the hell wouldnt we. In baseball, its considered an art form to steal signals. and untill the infamous 2007 memo, it was the same way in the nfl
