Cover-Up: Behind the Iran~Contra Affair (Documentary) 1988

"There exists a shadowy government with its own Air Force, its own Navy,its own fundraising mechanism, and the ability to pursue its own ideas of national interest, free from all checks and balances, and free from the law itself."
— Senator Daniel K. Inouye at the Iran Contra Hearings

This documentary deals with continuity of government, secret government, detainment camps, terrorizing citizens as means to political ends.
It's a history lesson and provides precedent to what we are seeing today under the Bush Administration.

*The volume isn't great in this documentary, but it was the best I could find. I wore headphones and it helped.
