Lawyer for DoJ argued actions taken in public while in possession of a smartphone afforded no expectation of privacy

The US supreme court is considering whether sprawling warrants for smartphone location data infringe on Americans’ privacy rights and violate the constitution.

Justices heard opening arguments in Chatrie v United States on Monday that concerned law enforcement’s reliance on so-called “geofence warrants” in difficult cases. The case was originally brought by Okello Chatrie, whose phone location data helped police in Richmond, Virginia, track him down after he robbed a bank at gunpoint and escaped with $195,000 in 2019. Chatrie pleaded guilty to armed robbery and was sentenced to 12 years in prison, but his lawyers argue none of the evidence against him should have been admissible in court.
