I agree completely with Jennifer's model. I think the important thing is that it needs to be indigenous-run and indigenous-led. Including law enforcement and getting them on board is, of course, key, but it can't be run by the police. It needs to involve and include the police, but it can't be run by the police.
I think the question that Jennifer asked, “Did you contact the police?”, is a key question. I think that's important to ask to weed out the people who don't want to be found or who are not missing.
Yes, there is definitely a role for police, but it's not a lead role in this process.
