If I could comment on that, I agree that obviously we'd like it to be zero per cent. When you're talking about something as complex as human behaviour, you're always going to find some people who, for one reason or another, are resistant to treatment or where treatment can't be delivered to them effectively. Not all treatment programs are the same.
In P.E.I., for the people who attend the treatment program here, if you look at the predicted recidivism rate without treatment for their risk level, it ranges from 13% to 17%. The five- and ten-year recidivism rate for people who have had treatment ranges from 3% to 4%. That certainly shows how effective it can be. I'd like to get it lower, but I don't know how much lower it can go.
