Excellent idea (and not just because I've suggested the same thing in the past!)

It's a good one, in that the government people involved can--we assume-- all move on or move over to more meaningful, productive activities on behalf of the beleaguered tax-payer.  

However, I suggest that a "turn-it-over-to-the-Natives" decision will get us even FEWER answers than we have now (See RCMP report on 2013 investigation.) One reason why: the "answers" provided by victim statements the chiefs and councils don't want us to hear would reflect terribly on their own peoples. It would render the "blame game" moot.
