He bought a gun because everyone else had one.

Calvin Jones, 18, bought a 9mm handgun for $100 on a street corner in Omaha, Nebraska.
Two days after purchasing the gun Jones proudly showed his girlfriend, Bria, his new bulletproof vest. While showing off his new gun he inadvertently shot Bria, leaving her permanently blind.
When a judge asked him why he bought the gun Jones shrugged and said, "Because everyone else has one."
Ohh shoot.
