Sixty one year old Georgia man named Roger Stephens was apparently fed up with a crying toddler while shopping at Walmart. Not one to suffer in silence (just look at that scowl!) Roger took matters to his own hands - literally:

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."
