There's an urban legend that when Al Capone's MA came to visit him in the rock. Ma Capone set off some metal detectors and was strip searched by the guards which would have been very traumatic for an old woman who just wanted to see her son one last time.
Why do I believe that story as opposed to the one about the troon who believed his bra set off the detector and be tsa used it as an opportunity to frisk him?...I mean besides Ma Capone being an actual woman?
Well because even back then metal detectors were calibrated specifically to ignore tiny bits of metal in certain clothes. Buttons, zippers and yes that includes the underwire and hooks in most ladies garments. Except Ma Capone was wearing an old fashioned corset and buttress when she came to see her son. One that at the time would have been almost 50 or so years out date, and have a lot more metal parts. More than what a modern detector could have been calibrated to go off over.
What's the point of me bringing this up I hear you ask? Well tldr unless Kevin and whoever that poster in that story was plans on wearing a corset... From the gay 90s (1890s) then any claims that tsa agents are being transphobes over troons wearing women's clothing in public are utter bullshit.
