The Supreme Court will soon decide whether geofence warrants violate the Fourth Amendment’s protections against unreasonable searches in a case involving Okello Chatrie, who was caught after a geofence warrant was used to track his cellphone location.
Chatrie had stolen $195,000 from a bank in suburban Richmond, Virginia, and eluded police until authorities turned to this powerful tool, which allowed them to gather location data from cellphones near the crime scene.
What Are Geofence Warrants?
Geofence warrants are a new tool in law enforcement’s arsenal that allows police to collect location data from mobile devices in a specific area around the time of a crime.
Unlike traditional warrants, which are issued after a suspect is identified, geofence warrants work in reverse. Police use them to identify potential suspects by gathering data from people’s cellphones who were simply in the vicinity of a crime.
The technique has been credited with helping solve cold cases and crimes where traditional methods, like surveillance cameras, failed. But civil libertarians argue that geofence warrants are essentially fishing expeditions, subjecting many innocent people to invasive searches of their private data because they were in the area of a crime.
The Legal Debate and Privacy Concerns
Chatrie’s legal team is arguing that the geofence warrant used against him violated his privacy because it allowed authorities to access the location history of people in the area without evidence of their involvement in the robbery. They contend that the warrant violated the Fourth Amendment, which guards against unreasonable searches and seizures.
Prosecutors counter that Chatrie had no reasonable expectation of privacy because he voluntarily opted into Google’s location history. The case raises questions about the privacy rights of individuals in the digital age, especially regarding data voluntarily shared with third parties.
Impact of Geofence Warrants in Other Cases
The use of geofence warrants has extended beyond criminal investigations into politically sensitive cases. For instance, law enforcement used geofence warrants to identify participants in the January 6, 2021, Capitol riot. Similar warrants were also used to identify suspects in killings across several states.
While the technology has been credited with solving crimes, it has also sparked concern about the potential for overreach. Some legal experts argue that if the Supreme Court rules in favor of allowing such warrants without clear judicial oversight, it could lead to a surge in similar searches, with potentially far-reaching consequences for privacy rights.
Chatrie’s Case and Legal Precedent
Chatrie, who was arrested after the geofence data led police to his location, pleaded guilty and was sentenced to nearly 12 years in prison. However, his defense team is pushing for the evidence obtained from the geofence warrant to be excluded, arguing that it violated his constitutional rights.
A federal judge initially ruled that the geofence warrant did violate Chatrie’s rights but allowed the evidence to stand, as the officer who applied for the warrant acted in good faith.
The Fourth Circuit Court of Appeals in Richmond upheld Chatrie’s conviction, while a separate ruling from the Fifth Circuit Court of Appeals in New Orleans declared that geofence warrants violate the Fourth Amendment.
This case echoes issues raised in the 2018 Supreme Court ruling that limited the use of cellphone tower data without a warrant. In that case, the Court ruled 5-4 in favor of privacy rights, acknowledging the extensive personal information collected by cellphones and the potential for abuse in digital surveillance.
