As I said in email to Kevin, “What isn’t said is that you can do the same thing to a room, building or airplane.” I know people who have taken down a house with a few cups of flour.
And how do you think it would work out if TSA were to test for flour, powdered sugar, and non-dairy creamer? Those powdered donuts you had for a quick snack before running to the security line would get you the full blue glove treatment. And as long as they don’t do those tests testing for conventional explosives and searching for knives, guns, and throwing away your shampoo is nothing but security theater.
