Thousand Standing Around (TSA) is afraid that your family might be packing several pounds of C4 masquerading as toe jam.

Of course, we all know that it can't be detected by "the wand".
If you're looking for logic behind the haraSSSSment, expect none. This agency is just like a spoiled child at times, beyond logic, compassion, or reason. And as a spoiled child, needs to be punished (preferably disbanded) for some of the asinine things they concoct.
