bus therapy
n.— «“I could be put on the ‘Merry-Go-Round,’” he writes. “In federal prisons, when a prisoner is en route, he’s not allowed phone calls or mail privileges. So what is sometimes done is that they put a fellow like me on a bus and drop him off at isolation for a few weeks at every prison they stop at. I’ve seen convicts caught up in that for nearly two years…Old convicts call it ‘bus therapy.’”» —“Prison Transfers Author of Critical Articles” by Bill Gordon San Francisco Chronicle (California) July 1, 1988.
