There's a lovely piece in today's (Saturday's) Guardian about a Canadian program, in which particularly difficult ex-cons (paedophiles, in the case discussed) are given new volunteer "families". \link{http://www.guardian.co.uk/comment/story/0,,1799618,00.html\Here}.
The ex-con has dinner at a different house every night of the week, and on the 7th night, everyone has dinner all together. The families make sure he is taking his meds. They help him sort out housing etc. They provide support and guidance.
Apparently this program has reduced reoffending rates by 60%, in a group of people very likely to reoffend. And those who do reoffend tend to reoffend for lesser offences.
It's a fascinating idea, although the article doesn't provide any contact info on the UK circles which are apparently starting up ...
