You can also politely ask to be escorted out, a request which will (and must) be granted, eventually. Walking out of the airport with police and TSA agents surrounding you like they are your secret service agents can be quite fun. It also gets the point across that such a "security" setup wastes everyone's time, including the TSA's.
