The last time I flew (which will be the last time until the TSA is dissolved), I went through the body scanner.
It was, apparently, set off by one of my tattoos. I was then accosted to a side office (WITHOUT my belongings) and told I could undergo a strip search (down to my boxers) there in the office or be arrested and deal with a full strip search. Under normal circumstances, given the threat made to me, I'd have taken the arrest, then gotten a lawyer, but I was trying to catch a flight to surprise my mum for her 70th birthday, so I did the office one.
20 minutes later, I was released, having nothing illegal, and returned to the checkpoint to get my belongings and catch my flight.
Among my belongings had been a "TARDIS key" necklace that I wore, which was given to me as a gift from someone very special to me.
It was gone. The TSA agent at the checkpoint had told me it had not been out of his sight the whole time and if the necklace wasn't there, I must have forgotten to wear it that day. Understand, going through that checkpoint had been the first and ONLY time I'd ever removed it.
