Children are not angels. Sometimes they break bad and have to be sent away for a while to a place where they can be broken of the badness, or simply be removed from a bad situation. (I know, I know, that's a huge over simplification, but that's how it seems.) We had a couple of homes for troubled youth in Tri-Metro and they were frequent visitors to the "liberry" along with their usual hulking, pro-wrestler style Troubled Youth Wranglers. Getting materials back from them was often a problem. Getting them to stop asking if we had The Anarchist Cookbook, an impossibility.
