@hawkeye10,
The full body scans are an outrageous violation of search prohibitions as outlined in the Constitution, and should be illegal.

No one have a right to have a driver license and no one have a constitution right to get on a commerce airplane either.
If you do not wish to undergo a full body scan then do not board a commerce aircraft.
The right of others not to get blown up out weight your rights to board a aircraft without such a scan if the government decide that is needed.
Take a train or a car or a ship if you wish to travel then.
