I'm sure you're not being disingenuous so I'll politely remind you of the part in each of those events where the deceased attempted to wrestle control of a firearm.
Why they commit crime at such higher rates than the White population would be an interesting conversation to have. Unfortunately, it seems as if you're implying that we shouldn't police them equally because of their race. I cannot endorse that, and I would urge you to consider their victims (most of whom are also Aboriginals, if they are your concern).
