Maybe this applies to your situation: Amendment IV The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
I am assuming that somewhere in the small print on your ticketing agreement that you have forfeited that fourth amendment.
