What I don't understand is, if someone steals something I own that has an airtag on it, how does airtags know if it has been stollen or "placed" on someone? In other words, it may appear if I'm trying to stalk someone instead of an item being stollen, thus the airtag will alert the phone that there is a tracking device nearby. Thus alerting the robber to find the tracking device and ditch it. I don't see how airtags will know when they are on a item that is stolen, versus being places on someone to track them. If there is not a way to diferentiate the two, then airtags are almost worthless.
