Public nudity is the answer. Voyeurs will no longer need to wear those X-ray glasses bought from a comic book ad. That will make those TSA screeners lives simple and exciting. No need for gender separate facilities and passengers on airplanes will put all their clothes in their carry-on baggage, which will be X-rayed for contraband. Passengers will be given their airline issue blankets to keep warm and, of course, hide any hanky panky. Pedophilia will no longer be a sanctioned behavior and extra-marital behavior will be acceptable. America will move to the promised land of Utopia where indiscriminate sexuality is something as acceptable as chewing gum.

Close to it speeds up screening. One day as I was pushing my luggage into the xray machine the woman behind me removed her top, apparently to avoid screening issues. She had her bra on, but it certainly caused the TSA to move her through quickly. They decided the metal detector would be fine, no need for the full body scanner.
She was clearly a frequent traveler, and just wanted to move through more quickly. It worked.
