SAIP: Guy in line at Walmart reaches into his pocket for his wallet and discharges his .40 Springfield, shooting (grazed) himself in the leg. Bullet then hits the floor and sprays a concrete shrapnel injuring a kid and her mom. The article says the weapon was "holstered" in his pants. I don't see how it was in a quality holster and this happens though.
Worst part was he then fled the scene. He is now under arrest.
Comments suggest that the offender doesn't have a current license. Either way, be careful out there.
