Without trying to detract from the point, I'd be interested in a viable call to action here. Police demilitarization is a good example of a call to action that has come out of #BLM. Regarding indigenous rights, should we be reconsidering the reservation system? Should we be seeking more complete integration, or the opposite, more complete separation?

I confess that I've read woefully little about this and would love a gateway in.

This article seems to be the source of this statistic. As they note, it's a hard number to come by because the crime is neither well-covered in the media nor well-reported by the authorities. Regardless, though, given the centuries-long and wildly painful indigenous struggle in the US, this certainly deserves our attention.

"Worried", maybe not. "Concerned" and "motivated", certainly. This is a problem we need to do something about it, even if my personal life is not immediately at risk. The fact that it may not be right in your back yard is no reason not to worry about it.
