Proposed missing adults law

I found this article about a proposed law that would require the police to actively search for missing adults if the adult is under 21, disappeared in a dangerous outdoor setting, had received threats or has been missing for over 30 days. That makes a lot of sense to me. I understand the vast majority of missing adults have left on their own, but the vast majority of those make themselves known within 30 days. And adults who disappear on a hiking trip or whatever, or who have gotten threats to their life, those cases should be investigated as a matter of course.
