I'm an aboriginal. I come from a community where these issues have arisen, and yes, alcohol and drugs are factors, but they're always just one factor. We have to look at things like residential schools, fetal alcohol syndrome, mental health issues. These are root causes for aboriginal people going to jail. You can turn today to the correctional investigative report that was just released. Howard Sapers, who is the correctional investigator, just released a whole document, a whole section, on discrimination against aboriginal people in the justice system, and if you turn there, all your questions will be answered.
On October 16th, 2006. See this statement in context.
