"I wouldn't bet on a cover-up by the Feds. They want to be the big hero (and that's OK) and would love a chance to trumpet a big find on live TV. There's no point in covering up stuff like this."
You are kidding.......right?
No... I'm not. If you think the Feds are just itching to cover stuff up and never show any real risk... then maybe you've seen too many movies.
