I've heard of multiple people using airtags to prevent and successfully recover stolen vehicles and property after armed carjackings, and as dystopian as that feels, it seems to me far less invasive to society to narrowly target violent criminals than hiring more beat cops to randomly pull over (disproportionately innocent and disenfranchised) people over miniscule driving infractions to hunt for the actual criminals…
Alternatively, if (with an actual warrant, and involvement of the airtag owner) the police could link location trajectories of any phones that travelled with the stolen airtag, that’d be nice. Not sure how to avoid abuse with that scheme.
