I had a break in at my house a few months ago, and one of the items they took was my passport wallet with an airtag in it. So I could see where they were. However, the address located was a multi-unit building, and the find my device was unable to pinpoint it to a single unit, and police apparently aren't allowed to get a search warrant for multiple units (understandable), but I wasn't allowed to trigger the sound to narrow it down further...

The air tag moved one morning, and it was found thrown over the fence...
