TSA Screener "Logic": Pax has a flat metal object, with four corners. It has the potential to be thrown in a flat horizontal or vertical trajectory narrower than an airplane isle at high speed while rotating to achieve flight stability and cause the corners to possibly break unexposed flesh of a person it should accidentally or on purpose strike. It obviously is a disguised Ninja Throwing Star, a BANNED object. Please step to the side, Comrade Criminal. LEO Assist!
