TSA and gapping hole are synonymous.
1) When I have to opt out or get a random I watch my bags like a hawk. If TSO complains about me moving out the area they ask me to wait in I remind them I keeping my possessions secure. Once when my bags were going out of my sight I asked a one stripper to get them for me (they did). The TSO in charge was miffed.
2) If you really wanted to conceal something you would just keister it. The TSA ain't gonna find anything where the sun don't shine. That is the gapping hole.
