What are my rights with TSA airport security?

Be aware that Transportation Security Agency (TSA) agents -- which are part of the Department of Homeland Security (DHS) -- are permitted to search you and your belongings without probable cause or a search warrant any time you pass through a TSA security zone.

For what it's worth, the TSA has a "Passenger Civil Rights" page, which includes information on filing a complaint if you believe your rights are violated. The TSA also maintains a blog, so feel free to post comments.
