My car got broken into and my iPad nicked. I was able to locate that, however, the cops here in NZ were really unhelpful.
They said the GPS location wouldn't be sufficient for a search warrant as they have had many cases of false positives.
I said I would give the ssid and ip address of their wifi network, even then they wouldn't agree for a raid.
It was only when the thief (who was a minor) took the pic of his family member, which I then furnished to the police (via iCloud), they could do something.
Wondering what good is technology, if the law takes a while to catchup, well at least here in NZ.
