The thing is, the city and province are going to make sure you get hundreds of such neighbours whether you like it or not, and they're also going to make sure the situations of those neighbours are as dire and intractable as possible, to maximize the frictions and to justify the service programs.
Call me old-fashioned but I still feel like habitual arsonists, shooters, parole jumpers etc. have issues that transcend their housing status. What I'm talking about is a possible alternative method for providing a basic form of supportive housing to people who need it and want it. Methinks the lumping together of such a wide range of individuals & personal circumstances is yet another device by which the authorities aggravate the overall situation and foster resentment and hopelessness.
