Well after 9/11 BrigadeQuartermaster sold a replica of OSS plastic made lapel knives that as advertised could pass thru metal detectors. They also had a disclaimer that read: "do not even think about bringing this item on board of the planes". What the hell are they thinking? Isn't it like giving a weapons and ideas away? This really suprised me because they always fly high the American flag and claim patriotism and devotion. Well maybe for the sake and safety of others this should have been taken of the shelfs. I found it really clever to have a memorial to 9/11 on one page and plastic knife that is more dangerous than any box cutter on the other. WHy don't they also list plans on how to build a gun out of synthetic materials or how to smuggle a bomb into different places... of course with proper disclaimer.
