Thank you, Waldo.
I think this is the part: "with particular attention to the circumstances of Aboriginal offenders." that gets people riled about the lenient sentences.
The courts also consider the circumstances of non-native people at sentencing. Thing is that white people are generally given more lenient sentences than natives as a matter of course. Consider this scenario, in Alberta:
30-year-old white guy in front of the judge for the third or fourth time on drug posession charges - probation.
17-year-old native kid next, first offense for drug possession, two years in an adult federal penitentiary.
This really happened to someone I know. This kid wasn't even off the reservation, was raised in a middle class white home, but he looked native and so the "justice" system treated him like one.
The thing so many White people fail to realize is that they've benefitted from preferential treatment in the justice system forever. This doesn't mean that no Whites ever go to jail or that non-whites never get a break; it does mean that if you aren't white, you are more likely to get a longer sentence than a white guy for the same crime. And if you are rich and White, even better for you.
