Many people are calling the cops to report that they are being tracked using Apple airtags.

The systems to inform people that they are being tracked with airtags are available only to people that carry an iMonster or an Android phone. However, to use those devices as protection from tracking is perverse, because they are tracking devices themselves. The phone network records its locations and stores that data for months.

IMSI-catcher devices (used by thugs at protests to identify protesters) track them locally, too.
