> Chatrie had opted in to an optional Google “location history” feature that documented his location every few minutes.
Google removed this feature last year because they were tired of dealing with these warrants. Now (Google says) your devices each store their own location history without centralisation.

...I smell a "backdoor" that's in the shape of the "Locate my device" and similar such systems. Unless there's no Android subsystem that will dredge up and present info about where a phone has been, then this demand seems totally plausible:
"We know that you can cause a device to report its historical location information. Cause all of the devices that were within area X between times T and G to report their positions during that time to us, the police. Here's our warrant."
Fantastic. One step closer to making holding personal data a liability.
