Spector and the Patriots

As much as I hate the Patriots I don't think it is a good idea for Congress to investigate them. I don't understand though why the NFL keeps letting Arlen Spector reveal things that they should have. First he was the one to say that the Patriots have been doing this since 2000. Now he explains how they actually used the tapes to their advantage. The NFL should be the one explaining these things, not a US Senator. Anyway read this for more.
