Surely it's a balancing act. Get to the kids whilst they are young and impressionable, to get them back on the rails, or ignore them and then complain as they become the teenage and adult thugs that really are a problem to society. The issue, at least for me, is not that there are "special measures schools" from public or private sector, but that the special measures schools are given proper licence to instil a sense of responsibility and discipline. That might mean the use of physical labour punishments (as described by Incognitas), something that no doubt many in our society would currently be wringing hands over.
