Interestingly I think that anti-government paranoia in the US is largely itself fed by all those movies in which some corrupt US government agency turns out to be the villain.

As a fun exercise, count the number of movies and TV shows in which the CIA is shown in a positive light. The FBI often is, the military usually is, the CIA almost never. Heck, the CIA has such a bad name in American movie land that on the odd occasion they want to show a good American spy (e.g. Die Another Day) they'll put 'em in the NSA instead despite the fact that the activities depicted are much more CIA-like than NSA-like.
