I mentioned this in another thread, but it's probably buried pretty deep. I applaud those in state and local legislatures trying to take a stand and enact laws banning the NoS from airports. However I fear it to be a symbolic gesture at most, the chances of success are minimal, and it will take a long time and spend even longer in court. So here's my alternative legislation proposal:

"It shall be illegal in the city/state of XXX to operate an x-ray device on human beings if not a trained and licensed medical professional with YYY certifications, under the direct supervision of a physician/dentist/other doctor allowed to have x-ray machine whose license is in good standing with the city/state. Furthermore, all x-ray equipment used on humans must be certified by ZZZ regulatory agency and calibrated every XYZ months."

In effect, every TSO on the NoS must have medical training and every checkpoint using the machines would require a doctor or dentist or they'd be in violation of city/state health ordinances. DHS case is much weaker, in my opinion, under this scenario than proposed legislation banning the machines all together.
