Last week's 6-3 Supreme Court decision in Chatrie v. United States ruled that a so-called "geofence warrant" compelling tech companies to identify every smartphone or similar device in a specific area constituted a legal "search" under the Fourth Amendment. It may not change the outcome of Okello Chatrie's conviction for robbing a Virginia credit union in 2019, but it could "send seismic waves through our Fourth Amendment doctrine," according to dissenting Justice Samuel Alito.
