The Unusual Suspect writes, "blogTO writes of a Canadian PhD student studying Social Political Thought who was intercepted by Kelowna Airport screeners when they spotted her necklace, which has a charm in the shape of a gun. (Article includes a photo of the actual necklace.) The charm is less than 2" in size, and has no moving parts."
Hey, Guy? If I could make a miniature gun that was 1.7" long and contained no moving parts and could still fire bullets, I could also make it in shapes other than gun. If your security seriously contemplates defending against that level of technology (firing bullets out of a solid object less than 2" long), then you'd better confiscate all metal objects, period. Also, what are you doing about other conceivable -- but technically impossible -- threats, like telekinesis, voodoo, and directed sunspot radiation? Link

"Who knows if there is a gun that small that can shoot bullets? You don't know that. They followed the rules."
