And if you think that the NSA/CIA need a warrant to spy on you in the interest of national security you're crazy. If I was detained at an airport under "national security risk" I could be detained without access to any of the liberties granted to me under the bill of rights. In fact, the US Marshals in coordination with the FBI and CIA grounded a flight and detained a reporter because a woman called in on him because he was taking 'Airborne' before the flight. The woman felt threatened of a chemical/biological attack. The man was roughhoused and was given no reason for his detainment and was question on the spot at gunpoint.
