Busted For Slapping Stranger's Crying Child
Georgia man, 61, threatened to "shut that baby up" at Walmart
SEPTEMBER 2--Meet Roger Stephens. The Georgia man, 61, was shopping Monday morning at a Walmart in Stone Mountain when he crossed paths with Sonya Matthews and her two-year-old daughter Paige. The child was crying, which apparently greatly perturbed Matthews. "If you don't shut that baby up I will shut her up for you," Stephens warned Matthews, according to a Gwinnett County Police Department report. Moments later, Stephens acted on his threat, slapping Paige "across the face approximately four or five times." Though the child "started crying and screaming" after being struck, Stephens told Matthews, "See, I told you I would shut her up." After police were summoned, Stephens told a cop that the child was crying "and he just slapped her," according to the report. Stephens was arrested for felony cruelty to children and booked into the Gwinnett County Detention Center, where he is being held without bond. Paige sustained "slight redness to the face," but was otherwise unharmed.

People, please don't bust other people's kids upside their heads. That's their job (no matter how ill-mannered their child may be) - not yours.

Lesson: If you hit my kid and I don't know you, I will fight you in the middle of [insert Store name here]. That is all.
