I don't see why the police can't just get a warrant - "the victim is showing me a tracking pin showing their device" seems like reasonable cause for a narrow search warrant to be issued on a property for that device.<p>This seems like a reason to streamline warrants rather than bypassing the normal court oversight processes.
This seems somewhat fair, it'll end the 'we can't do anything, even though your 'find my device' shows exactly whose house it is in' reply from the police. Given the size and scope of mobile theft something need(ed/s) to be done.
