There's always the debate around incentives and disincentives and what works or what doesn't work.
When I look over the last five years, in terms of the kinds of measures we've put in place coupled with the treatment programs, and particularly offenders who are going out into the community and who have conditions to abstain from the use of substances, the number of individuals who are violating that condition is being reduced. Once they're out in the community, offenders see the advantages of being out there. They don't want to come back to my big houses. They want to stay out. So, we are seeing a reduction.
About five years ago around 4% to 5% of offenders who were out on day parole, full parole, were being revoked for violating their abstinence clause. Last year that was down to 2.8%. The combination of the approaches we're using, the detection methods we're using, the treatment programs we're offering, and the maintenance programs are driving those numbers down. We still have a lot of work to do, but it's moving in the right direction.
