Let's review. 
Sometime around 2014 
"RCMP said close to 90 per cent of all female homicides are solved, and there is little difference in solve rates between aboriginal and non-aboriginal victims.
Overall, the RCMP review -- drawing on data stretching back to 1980 -- identified 1,181 police-recorded incidents of aboriginal female homicides and unresolved missing aboriginal females -- 164 missing and 1,017 homicide victims."

Harper correctly concludes that the "murdered and missing" inquiry wasn't needed because there was no mystery to solve. 
Usual epithets are thrown his way: racist, divisive, mean-spirited etc etc 

"I want my Canada back" Trudeau promises inquiry.
Hooray!
So far $50M spent mostly to line the pockets of the usual suspects in the Indian Industry. 
Meanwhile there really isn't any inquiry at all.
(because the Libs also know there isn't any need) 

So.
No inquiry vs No inquiry +$50M (and counting) wasted. 
What a country.
