There are a few airports (BDL is one) where the screening of checked luggage is done in front before the bags are sent off to the bowels of the airport and so you can be present for the screening.

Whenever I travel from BDL, I ALWAYS, much to the annoyance of the TSA people there, watch my bags being screened. I stand nearby inside thyeir little roped off area and if any of the bags have to be opened (and they often do because pancake syrup and peanut butter are such hazards to aviation safety), I watch them unpack my bags and mess around with my belongings, politely making repacking suggestions. And once they are finished I apply my wire ties to lock the zippers closed. I know this annoys the TSA people, but I do not care. I am always polite. Because I had carefully packed my bags, I expect them to respect that and carefully repack them if they open them and I make that known to them when necessary. I do not leave the area until my bags are placed on the conveyor belt and disappear through the magic door into the unknown, past the check-in counter and the TSA people.
