The District of Columbia’s efforts to pull its children from a Massachusetts shock-therapy clinic have been stymied by recalcitrant parents who don’t trust school officials’ intentions, the city’s top lawyer told The Examiner on Tuesday.

Peter Nickles, the city’s acting attorney general, had promised publicly to have all 10 of the District’s children pulled out of the Judge Rotenberg Center in Canton, Mass., by March. But at least four of the parents have resisted D.C. officials’ efforts to move their children to new schools, Nickles told The Examiner on Tuesday.
