They can search each laptop for possible terrorist-type writing and confiscate cell phones, white powder, shoelaces, car keys, pencils, anything sharp or cylindrical or made of glass, and interrogate people randomly, putting them naked into cold rooms with ugly music played at top volume. It's all fine with me. I'm a liberal and we love ridiculous government programs that intrude on personal freedom. But where are the conservatives who used to object to this sort of thing?
Alas, the conservatives have been replaced by Republofascists who make up agencies with names like Department of Homeland Security, and the country is worse off for it.
