It seems to me that lots of people called for a public inquiry into missing and murdered indigenous women.  Well, this is what a public inquiry looks like:  standards of evidence, witnesses called to testify with either first-person experience or expert assessments, and a quasi-judicial structure.

If you didn't want those elements, maybe you should have called for something else.  Personally, I think that having those things would be useful, if you want meaningful recommendations to result from the process.  If you don't, then feel free to have something else.
