Comment "Could be used to create explosives" (Score 2) 431
I'm sure they did find substances that could be used to create explosives -- heck, let's call a spade a spade, and acknowledge that they're precursors. Things like:
Water -- simply pass an electric current through it to generate a tremendously explosive mix of hydrogen and oxygen gas.
Air -- a critical component, and by far the major component by volume, of the infamous "fuel-air explosive".
Aluminum foil -- ball-mill it long enough, and it becomes dark aluminum, a controlled substance used to make flash powder.
Lunch meat -- a plentiful source of animal fat, which can be saponified to produce glycerine, which can be nitrated to form nitroglycerin.
Books and other printed material -- almost always printed on paper, consisting mostly of cellulose, which can be nitrated to form nitrocellulose ("smokeless powder").
I could go on in this vein at great length, but why bother? I've already outlined the case against anyone on the surface of the planet, or off it for that matter.
