That's the best and most hilarious part. Even after having months to tamper with the evidence they will still leave crumbs that will prove it was a total sham. Faking something that massive isn't easy. Its especially hard for people that got their job not because they are the best at it but instead because they are the most corrupt or easily bribed etc etc. Its the one flaw I've noticed in how these people function. Nothing is based on merit thus they fail upwards. Once at the top they just fail...

The only exception I've seen to that rule so far is Obama. He really was a sharp leader. His problem was he was smart enough to realize he was surrounded by failure so he tried to micro manage everything... which never works, especially when you are giving orders to idiots.
