As you said, it's a very special case. It isn't always possible to make generalizations based on a very special case.
Maison Painchaud has been around for 53 years. You can imagine the thousands of residents who have been housed and guided by Maison Painchaud over the past 53 years. As far as I know, in 53 years, only one person has committed a murder during their stay at the halfway house: Eustachio Gallese. It's really a special case. I find it unfortunate that generalizations are being made based on the case.
The direct supervision model has been implemented and tested in Quebec since the 1980s. Year after year, the assessments conducted by the CSC with organizations that carry out direct supervision have always been very good and complimentary regarding the work accomplished. The work was accomplished as a result of the joint efforts of the CSC staff, the parole officer and the parole officer supervisor.
If direct supervision weren't working or had serious shortcomings, the recidivism rates would be much higher than the rates presented to you.
