Point taken. Boom bad. No boom allowed on plane.

So, TSA employees get a lovely demonstration of how powerful explosives can be. Useful to drive the point home, I suppose, since anyone who has no military or civilian explosives experience doesn't necessarily know exactly how powerful various explosives are in the wild.

Does this training include an explanation of the concept of cross-contamination, so TSOs know that they can swab just one item in a bag, not every little piece, to test for explosives residue?

Does this training include mention of the fact that there is no liquid explosive that can be mixed airside or airborne without laboratory conditions that has the slightest prayer of bringing down a plane?

Does this training include more extensive instruction in the detection and recognition of explosives, i.e. the ability to tell whether you're looking at C4, toothpaste, or cake frosting?

Does this training provide any actual training at all, or is it simply a testosterone-fueled demonstration of various things that go boom?
