I wonder how much money some folks are making on this. As I pointed out it does nothing to stop anything as the bad guys can steal or buy what they need afterwords. The reasoning I heard was the underwear bomber. A hand held or rack mounted explosive sniffer (military grade) is 35,000 dollars as opposed to a multi million dollar full body scanner. So where is the tax dollar going under the illusion we are safer? So you keep a guy from bringing in a knife, and he walks down the hall and steals one from the restaurant ... so where exactly does the justification for the multi million dollar scanner come in
