I already know exactly what&#x27;s going to represent a &quot;security consideration in order to safeguard transportation security.&quot;<p>When you opt-out, they make you wait a <i>long time</i> standing next to the X-ray machine for someone to give you a pat-down.  (It&#x27;s almost never that the guy doing pat-downs is busy, btw- really weird.)<p>They&#x27;re going to claim that having someone wait near the X-ray machines that long represents some kind of security threat.  And then they&#x27;re going to use that fact to justify overriding the opt-out, because the more time you spend next to an X-ray machine, the higher the odds you&#x27;ve tampered with it or have had time to assemble that tactical nuke you&#x27;ve been hiding in your pockets or whatever nonsense they come up with.
