You see, TSOs could slip a laptop, netbook, or tablet down their pants (and have), but even the largest TSO would have a difficult time stuffing an entire carry-on bag/laptop combination down their pants, and waddling away form the c/p, without someone noticing.

Is that a stolen carry-on bag with a laptop locked to the outside of it, or are you just glad to see me?
