Demand legal declaration that x-ray, millimeter wave, thermal and other advanced imaging technologies are an unreasonable search. No x-rays without a warrant, not in the airport, not anywhere. The machines only get 'better' from here. TSA is only the start.
Without such a declaration the 4th amendment becomes meaningless in the face of advanced imaging technology.
These machines are never going to become less detailed or invasive, only more widespread, more difficult to detect as they are miniaturized.

Write your Senator, Write you Congressmen. Write your Paper.
We must not allow the combination of technology and fear to entice us to compromise our way of life in search of an illusory veneer of safety.
