Police like using Google data to solve crimes. Does that put your privacy at risk?

Queenie Wong recently reported:

After a man was shot dead outside a bank in Paramount in 2019, Los Angeles County sheriff’s detectives turned to Google for help identifying suspects.

Through a search warrant, detectives directed the tech giant to provide cellphone location data for people who were near places the man visited on the day he was killed. The data Google provided eventually led detectives to two suspects who are now in prison for the murder.

But law enforcement’s demand for Google location data using what’s known as “geofence warrants” also sparked concerns that the requests violated the suspects’ constitutional rights. This year, a California Court of Appeal upheld the murder conviction but ruled the warrant violated the 4th Amendment, which prohibits unreasonable searches and seizures, because it was too broad and could have potentially swept up thousands of people.

The case, People vs. Meza, highlights the central tension over the exploding use of geofence warrants: Law enforcement leaders see Google location data as essential for solving crimes, but civil rights groups fear such warrants will infringe on the privacy of innocent bystanders.
