My step mother was a TSA screener back when the agency first formed. She was able to carry full sized blue guns and large fake explosives through security, while wearing her id card, without it being detected when doing penetration testing. The TSA agents usually couldn't even spot their own coworkers playing the role of terrorist even though they worked together on different shifts. She left after several months of very low quality coworker antics and the like. She has no respect for that job.
