Joke&#x27;s on you: It seems that when the TSA get really busy, such as at Seatac on 12&#x2F;19 at 6am, they simply shut off the body scanners and switch to a single dog sniff and metal detectors. I didn&#x27;t even have to take off my jacket or shoes! Which only serves as further evidence in my mind that the imaging devices are bullshit and the TSA knows it.
