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.
She was a weirdo. A frequent traveler would have had more sense. She sounds like someone trying to make a statement probably had someone videotaping it and then claimed how she had no choice as to avoid the scanner. Oh the drama!
LOL! By removing all clothes, the passenger will be able to streak through the screening!
