Police Using Google Data

"To find suspects, police quietly turn to Google":

In at least four investigations last year – cases of murder, sexual battery and even possible arson at the massive downtown fire in March 2017 – Raleigh police used search warrants to demand Google accounts not of specific suspects, but from any mobile devices that veered too close to the scene of a crime, according to a WRAL News review of court records. 

I'm guessing this isn't confined to Raleigh, NC. (Via Debby Witt.)
