I really wish all the thousands of people in their cars and on the subways each day were screened as well. Any one of them could have a bomb and kill thousands more. After all, driving or riding the subway is a privilege, not a right and I think doing either gives implied consent to be thoroughly searched. The same goes with walking down the street or shopping in stores. Neither of these is a right, rather a privilege and it would seem that the same implied consent is given that one be searched before stepping on a sidewalk or entering a store. Further, I live in a multi-unit building. Any person here could be a terrorist. Renting and property ownership are privileges, not rights and each person, I believe, gives implied consent to be searched before he or she enters the building. Dozens of lives are at stake.
