As regards the Canadian police (especially, but not limited to the RCMP) they are no angels. Especially if you are indigenous/autochthonous. And that's because they are fulfilling the function for which they were created: taking land and living away from some people. A quick google on the history of the RCMP, their recent shoot-to-kill policies at indigenous roadblocks, the colonial/imperial origins will put Justin Trudeau's hypocritical taking a knee into perspective.
If you really want to feel sick read-up on the Highway of Tears and the systematic brutalization of indigenous women by Canadian society.
