Screener Sends Himself Through X-Ray DENVER - A security screener at the Denver airport has been disciplined for sending himself through an X-ray machine. "I cannot ascribe any sort of motive to why anyone would do this," said Mike Fierberg, spokesman for the Transportation Security Administration. Fierberg would not release the screener's name or detail the punishment. "The screener in question did not jeopardize the safety of any passengers or aircraft," he said Monday. "But it was clearly behavior that is not acceptable."
