Yeah, it's good to know--but now the ACLU knows and that means a civil rights lawsuit that will try to end the program.
Anyone out there disagree with that?
ACLU really has no case and probably won't make a fuss. There's no expectation of privacy while in a public place. Police take pictures of demonstrators all the time. Surveillance cameras capture images of people walking along the street all the time. Really there's no invasion of privacy.
My two-point explantion of why no lawyers ever objected to preflight baggage inspection:
1. Lawyers fly.
2. Lawyers' mothers fly.
