According to D.C. police, 420 juveniles taken into custody on armed-robbery charges in the city this year had been arrested before. Including the robbery case, 144 of them have been arrested twice; 102, three times; 74, four times; 44, five times; 29, six times; 10, seven times; five, eight times; five, nine times; three, 10 times; one, 11 times; one, 12 times; and two, 14 times.
"You do a robbery and get caught for the
fifth time, and they send you to Oak Hill," Ramsey said, referring to the city's juvenile detention facility in Laurel, "and you stay for three months.

"Then you get released to a group home, and nobody tells us that you've been released because juvenile court proceedings are secret. We know nothing about your release until you get arrested for the sixth time. To most of them, it's just a joke."
