A few years ago Maricopa County Arizona had a seperate DUI Court for Native Americans and Hispanics~ this DUI court was consistantly handing down lower fines and lighter sentences than the regular court. I know people pitched a fit when they figured it out but don’t know if it is still happening. The justification of the seperate court was cultural differences about drinking.

Notice there is a link to "curriculum" on that page, although the curriculum page has no actual curriculum, since they need to hide that from the taxpayer. It does have the key phrase "social justice", though.
