This is about accountability , first nations peoples want answers and so do most right minded Canadians . They also want proper investigations about the mass graves that they have known about but said f**k all about They want DNA testing to identify these children and how they died. Its raw as f**k right now, many folk don't think there is enough done by the government to investigate and even take down monuments of people responsible for the residential school system.

Google the Highway of Tears , at least 40 indigenous women went missing on an isolated highway way up north over a period of years, also Robert Picktons pig farm murders ....clear systemic racism.
