I think the GP comment had a point, before you get to a gate you are scanned/x-rayed, searched and pass by chemical sensors. This is not to mention other technologies that are baked into the surveillance system. I think fretting over a bag past that point is a little much. Frankly, the crowded snaking lines leading up to the TSA are where one should be concerned.
