Re: Bricked trying to organize a protest...
Law enforcement in the US doesn't show much interest in recovering stolen phones. In large part because States don't prosecute their theft as a felony, regardless of the phones value. They'll prosecute the robbery/mugging or the breaking and entering/unauthorized access to private property if they can, but unless they actually catch you selling it, the actual phone might get you petty theft or unlawful possession. Even then they often successfully argue they'd just found the phone and hadn't reported it, most States give you 48 hours to report found goods. Unless you can positively ID the person for robbing you, it is hard to prove they didn't just find the phone.
Also, giving law enforcement search and seizure authority based in consumer GPS data is a stunningly bad idea, especially in high density areas. Although fairly accurate, their official tolerances aren't right enough to serve as legal data. Although the device seems to be in Apt. 313, it could be anywhere within 50' and in six or seven different residences. The police can't be coming in my home because my sketchy neighbor stole your daughters phone.
Even in targeted GPS tracking operations where they use higher tolerance devices, the evidence by itself usually isn't admissible as stand alone evidence. It is used as corroborating evidence of a crime they've got other evidence for.
I'm not sure what the solution to phone theft is, but giving the police more power isn't the right answer.
