It was almost a routine event. An armed robbery occurs every few hours in Atlanta. The damage was relatively slight in this case: a woman temporarily hospitalized, a trembling store clerk vowing that he will quit his job as soon as he can find another way to pay his college tuition. The "suspect in custody" received 10 years in prison, but he had been there before. He was nine years old the first time he got busted, for stealing a baseball bat, and he spent three months in a Dekalb County juvenile facility waiting for the court to find him a foster home. Now his record, as the police say, is as long as your arm.
