If security personnel at the airport ask to examine your cell phone, they have a good reason.

Take a look at this:

Supposedly, these cell phone guns are not in the U.S. yet,
but they are in use elsewhere.

Beneath the digital phone face is a .22 caliber handgun capable of firing four rounds in rapid succession using the standard telephone keypad.

European law enforcement officials are stunned by the discovery of these deadly decoys. They say phone guns are changing the rules of engagement in Europe.

Only when you have one of these phones in your hand do you realize that they are  heavier than a regular cell phone.

Yikes!
