Warren Sapp claims on his twitter account that he "just found out" who the snitch was. He claims it was Jeremy Shockey.

To begin with, Sapp stated he, "just found out who the snitch was." Someone asked "Shockey?" And his reply was "Bingo!" I hate Jeremy Shockey now, not just because he's the snitch but because how petty and self-centered he's been his entire career. When a season-ending injury forced him to miss the Super Bowl when he was with the giants, Shockey grew a gargantuan chip on his shoulder for no reason that I can figure out. And then when the Saints released that aging bag of bones prior to the 2011 season, maybe he decided to exact revenge.

Granted this is still nothing more than conjecture until all the facts are known. But as of now, Jeremy can go fly a kite for all I care. What a loser!
