Program Summary:
The Supreme Court held in Chatrie that the government's use of a "geofence warrant" to obtain Google location history was a Fourth Amendment Search, and that people have a privacy interest in their cell phone location history--even when it's stored by a third party and even for a short period of time. The ruling has potential impacts for a wide range of surveillance technologies. Join NACDL's Fourth Amendment Center (Mike Price, co-counsel for Mr. Chatrie) to discuss the decision and how to apply it to your cases. The webinar is free and open to all defense lawyers.
