why does congress want to look into"spygate"?

[Daseal]

I will say this about the spygate scandal. Why on earth did Goodell a) order the tapes destroyed. b) tell the Patriots to destroy them and not oversee the process.

I can't fathom why these tapes don't get locked in say a safety deposit box, or somewhere on lockdown at NFL films. You don't want folks getting into them, but I feel it's important to keep the evidence around. At least for a year or two.
