As cool as it is ingenious, the Cell Gunphone will give security officials even more to worry about. On the outside, it looks like any other cell phone, but lying beneath the exterior is a .22-caliber pistol that's capable of firing four rounds in rapid succession. Twist the phone, load up the top half with .22-caliber bullets, and fire away using keys 5-8.
“We find it very, very alarming,” says Wolfgang Dicke of the German Police union. “It means police will have to draw their weapons whenever a person being checked reaches for their mobile phone.”
