Sorry to say it, but the searches have been ruled legal and constitutional. Although the 4th Amendment requires reasonable suspicion, the courts argued that boarding an airline flight has implied consent to be searched (hence the signs about how bags and passengers are subject to search.)

My objection to the randomness is that it's inefficient and expensive. We're adding 2-3 extra employees per flight to randomly screen people... but what do we gain from this?

I also think it's humiliating. I hate it myself, but I've seen passengers burst into tears as they're yanked out of line.

Not to harp on the medical metaphor, but look at it this way: if I were to take five random people and give them physical exams, odds are I'd find absolutely nothing. But if I took five people who felt "under the weather" or had some sort of symptoms, it would be a higher-yield enterprise.

As I mentioned in another thread, there is hope. Now that TSA Director Loy has put an end to breast milk drinking and perhaps to the pointless security questions, he may well end the random screenings... or at least cut back.

My advice is to speak up! Write to the FAA, the TSA, lawmakers, etc... even a letter to a local paper is a step in the right direction.
