From an airport policeman in Minneapolis responding to this:
Airport police said a security screener was waving a metal-detecting wand over [Daryl] Miller's pants area on Friday when Miller pulled his shorts down to his ankles. He wasn't wearing any underwear.
Miller then said, "There, how do you like your job," thus ending the screening, according to the police report. He was charged with indecent exposure and released on $300 bail.
Looking for something sensible in airport screening? Try this.
But back to that first quotation for a second. So in this cop's mind the only thing that's keeping all of our pants on is the threat of getting arrested? Strange, because it's been my experience that, even in instances where indecent exposure laws don't apply (like a dinner party) people tend to keep their pants on. Maybe I just have prudish friends.
