I was flying out of CAE, which is near Fort Jackson, an Army training base. There is heavy military traffic through this airport. A young woman, obviously in the military although not in uniform (travling with others in uniform) was having her bag swabbed. It tested positive. She realized that the bag she was using was the same bag she uses at the firing range.
They searched her bags and sent her on her way. No big deal. I guess being used to the military traffic, similar incidents may have occurred.
Nice to see them use common sense.
