Trying to boycott the scans when at the airport will likely get you in trouble, rather than bring change at the TSA. Boycott the airlines. Stop flying. Use "Go to Meeting," or similar software, or drive or take the bus or the train. If we as a people did that, even for only a few days, the airline industry would be screaming at the TSA, and the abusive practices of the TSA would stop. Let the airports be empty for a day, and see what happens. The pressure that would be brought to bear on and then by Congress would be enormous. If we bring enough pressure on Congress we might be able to accomplish the same thing, but maybe not. They have ignored the will of the people frequently the last two years. But let the airlines be on the brink of financial disaster, and the risk of the entire industry collapsing would drive Congress to act.
