Missing and Murdered Inquiry. I was hoping for a pragmatic approach - develop a straight forward list of all those people who claimed to have lost dear ones - who they were, when they lost them, where they lost them. Check the list against all of the investigations and missing reports - and see what's left over. Were there an average of 40  a year over 30 years (1200) - of which the solve rate was about 90% and almost the same for non-indiginous? Or was the total much, much greater? Why has it taken so long to simply quantify the "problem"? Seems that's the first thing you should do when people refuse to believe the statistics they've been given. You could even do an incremental collection - Nation by Nation and see if a pattern emerges. This not rocket science if indeed you're looking for "evidenced based" solutions.
