The tracking function is apparently a very helpful law enforcement tool.
Apple’s Find My feature is immensely useful. If you’ve ever been out for a wild night of drinking and wake up the next morning without your phone, Find My is there. If you are in a hurry and dash out of your Uber only to later feel a suspicious absence in your pocket, Find My is there. And, if you’re a British law enforcement team conducting a probe into a massive iPhone smuggling ring in the heart of London, Find My is also, apparently, there.
