I think the way the alert system currently works in the provinces is that it's generally managed through their emergency management services. Decisions on whether or not alerts go out are made by the police force.
I think having family members or representatives of the community at the table when making those decisions is critical to ensuring trust, and then, if it is determined that an alert doesn't go out, there should be a measure in place so that there is an opportunity to review, alongside the community, whether or not that was the right measure to take.
