They'd only be doing this for a tiny percentage of phones that travel through checkpoints, though- and it's not clear to me what they would be looking for.

If there was a real motivation to secretly snoop on every phone that passed through a TSA checkpoint they'd come up with a better excuse that would allow them to plug in every phone- or they would more likely just be upfront about it. They haven't really tried to be sneaky about any other invasive screenings, to my knowledge.
