Things I Don't Understand, part MCDLXVII

Why does Arlen Specter care that Bill Belichick has been taping since 2000? He’s all upset that the NFL destroyed tapes, but as far as I can tell, it was the existence of the tapes, not their content, that was the problem. Belichick and the Pats were found guilty and penalized. Why not destroy the tapes? Doesn’t Specter have anything better to do?
