I have heard that the m16's those Guard guys carry around the airport aren't even loaded. It's presumed that the mere presence of the soldiers will deter criminal activity, which is probably true for amatuer criminals but not for pro's.. .If you walk in to Ben Gurion at Telaviv you won't "see" a single armed individual but the place is loaded with highly trained security professionals armed to the teeth.. .How many more jets are we supposed to lose before the government gets serious about security?
