I have heard of terrorist cells, but now we have to also worry about terrorist cell phones.
And here is a demonstration of it in use.Recent terrorist attacks against the United States and the discovery of a shipment of cell phone guns in the West have made airport authorities worldwide scrutinize mobile phones. The improvised cell phone guns – digital phones that harbor .22 caliber handguns capable of firing four rounds in succession with a standard telephone keypad – were apparently not used in the hijackings of American aircrafts on Sept. 11. But many airports are jacking up security against them anyway.
