There are NO laws that require airlines to have TSA personnel screening passengers--they just moved in, set up shop, and began molesting people under color of law.
Also, TSA "agents" are NOT sworn LEOs. They are, effectively, a cross between the private security force of DHS and the "in the field" regulatory arm of an agency that is NOT under DOJ.
What this really boils down to is that the airlines have been bullied into letting a cadre of non-sworn, unconstitutional, sociopathic thugs invade their PRIVATE PROPERTY and regulate their businesses and harass their paying customers.
The TSA is no different that a Mafia protection racket. They threaten legitimate business owners with fines, imprisonment or worse, and then move in and begin harassing and shaking down the locals (customers)...
It needs to end. And the ONLY thing that needs to happen to end it is for the airlines to tell them to leave their private property, and hire legitimate, well-trained, and respectful PRIVATE security companies to do their screening.
Don't fly. But if you do, OPT OUT of the naked body scanners, and then INSIST that they conduct their "grope-down" in full view of the assembled masses.
Men who fly wearing kilts (Regimentally, of course!) is also a GREAT idea, and if I fly in the near future, I plan to don my favorite SportsKilt specially for the trip...
I'm currently working on a design for t-shirts and card-stock luggage inserts printed with special inks that are invisible to the naked eye, but show up on x-rays. As soon as I get the designs finalized and get the special ink in-hand, I'll post pics of the designs, and let you folks know how you can get them.
Let's just say that the "secret messages" I'm working in to the designs are NOT polite, complimentary, or civil, and hopefully will make these illegitimate thugs stop a minute and think about exactly what it is they are doing and exactly what they are turning this Nation into...
