in answer to your first question, i have no idea. i do know of people who have paid off fines at a rate of £1 a week & similar, but how enforceable this is when you're dealing with people of no fixed abode i wouldn't know. as for aversion therapy, well ... i don't really like the idea of anyone being beaten with anything! *cue fluffiness about there needing to be more resources put into specialist drug & alcohol treatment programmes, as well as into tacking the root causes of homelessness and substance abuse etc etc*
