I used to have a bit of an interest in recreational lock picking.  I had a few TSA-approved locks that I liked to use as demonstrations to friends, because they were so trivially easy to open.  They would pop open after just a few seconds of jiggling anything at all around in there, so they were great at building people&#x27;s confidence that they could learn to pick locks, and that locks are just puzzles, not magic.<p>This is the only time that I&#x27;ve ever considered the TSA locks to be useful for anything at all.
