Right, but you have to remember that the people running these institutions are routine subjecting their inhabitants (a fair portion of whom are innocent and/or unfairly convicted) to all kinds of unpleasant things they'd prefer not to "receive", to wit: rape (via silent acquiescence), beatings, gratuitous solitary confinement, intentionally inadequate food provisions, routine humiliation, etc.

So in cases like these, a bit if turnabout is more than fair play.
