First, the Catholic Church took your money to keep the little man in the red Spandex away. Then, the Mafiosi took it to keep the arsonists away. Now, TSA is taking it to keep the blue gloves out of your, ejem, personal property. They are allowing people to buy their freedom from unreasonable search and seizure because money-makes-right is so much better than might-makes-right.
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.
