Supreme Court weighs phone searches to find criminals amid complaints of ‘digital dragnets’

WASHINGTON— A man carrying a gun and a cellphone walked into a federal credit union in a small town in central Virginia in May 2019 and demanded cash.

He left with $195,000 in his bag with no clue to his identity. But his smartphone was tracking him.

What happens next could lead to the Supreme Court making a landmark decision about the 4th Amendment and its restrictions on “unreasonable searches.”

Typically, police use clues or clues to find suspects, then seek a search warrant from a judge to enter a home or other private area to seize evidence that could prove a crime.

Civil libertarians say the new “digital networks” work in reverse.

“First we’ll take the data and investigate. Then the suspicion. That’s the exact opposite of how our system works, and it’s really dangerous,” said attorney Jake Laperruque. Center for Democracy and Technology.

But these new data scans could be effective in finding criminals.

A police detective with no clues in a Virginia bank robbery resorted to what one of the judges in the case called “a groundbreaking investigative tool that enables the relentless collection of frighteningly sensitive location data.”

Cell phones can be tracked through towers, and Google stores this location history data for hundreds of millions of users. The detective sent Google a request for information known as a “geofence order,” which refers to a virtual fence around a specific geographic area at a specific time.

The officer searched phones located within 150 meters of the bank at the time of the robbery. He used this data to locate Okello Chatrie, then executed a search warrant at his home, where cash and robbery notes were found.

Chatrie filed a conditional guilty plea, but the Supreme Court will listen to your objection On April 27.

The justices agreed to decide whether geofence permits violate the 4th Amendment.

The result could go beyond location tracking. More broadly, the issue is the legal status of large amounts of privately stored data that can be easily scanned.

This may include words or phrases found in Google searches or emails. For example, investigators may want to know who called a particular address in the weeks before an arson or murder occurred there, or who sought information about the making of a particular type of bomb.

The justices are deeply divided on how this fits into the 4th Amendment.

Two years ago, the conservative U.S. Court of Appeals for the 5th Circuit in New Orleans ruled that “geographic containment permits are general permits that are categorically prohibited by the 4th Amendment.”

4th Amendment historians say the constitutional ban on “unreasonable searches and seizures” stemmed from anger in the American colonies at British officers who used general warrants to search homes and stores even if they had no reason to suspect anyone of a crime.

National Assn. Criminal Defense Lawyers rely on this argument when challenging geographic restraining orders.

His lawyers argued that the government obtained Chatrie’s “private location information… through an unconstitutional blanket order compelling Google to conduct a fishing expedition through millions of Google accounts without any basis that any of them might contain incriminating evidence.”

Meanwhile, the more liberal 4th Circuit in Virginia split 7-7 to reject Chatrie’s appeal. Many judges declared that the law was unclear and the police officer did nothing wrong.

“No search was conducted here,” Judge J. Harvie Wilkinson wrote in a concurring opinion defending the use of this surveillance data.

He pointed to Supreme Court decisions from the 1970s that held that check records kept by a bank or call records kept by a telephone company were not private and could be searched by investigators without a warrant.

Chatrie agreed to have location records kept by Google. If several months’ worth of financial records are not private, “certainly a request for a two-hour snapshot of one’s public movements is not private either,” the judge wrote.

Google changed its policy in 2023 and no longer stores location history data for all its users. But mobile phone carriers continue to receive warrants requesting tracking data.

Wilkinson, a leading conservative of the Reagan era, argued that it would be a mistake for the courts to “impede law enforcement’s ability to keep pace with tech-savvy criminals” or “cause more unsolved cases to go unsolved.” Consider a murder in which the criminal leaves behind his encrypted phone and nothing else. No fingerprints, no witnesses, no murder weapon. “But a geofence order could solve the case because the killer allowed Google to track his location,” he wrote.

Judges in Los Angeles approved the use of the geofencing order Finding and convicting two men of robbery and murder in a bank parking lot in Paramount.

The victim, Adbadalla Thabet, collected cash from gas stations in Downey, Bellflower, Compton and Lynwood early in the morning before heading to the bank.

After he was robbed and shot, a Los Angeles County sheriff’s detective found video surveillance showing him being chased by two cars with obscured license plates.

The detective then sought a geofencing order from a Superior Court judge, asking Google for location data for six designated locations on the morning of the murder.

This led to the identification of Daniel Meza and Walter Meneses, who admitted to the crimes. A. California Court of Appeals rejected 4th Amendment claims in 2023, even though the judges said they had legal doubts about the “novelty of the surveillance technique at issue.”

The Supreme Court was also divided on how to apply the 4th Amendment to new types of surveillance.

The court ruled by a 5-4 vote in 2018 that the FBI must obtain a search warrant before demanding a cell phone company turn over 127 days of records for Timothy Carpenter, a suspect in a series of store robberies in Michigan.

The data confirmed that Carpenter was nearby when four of the stores were robbed.

Chief Justice John G. Roberts, joined by four liberal justices, said this lengthy surveillance violated privacy rights protected by the 4th Amendment.

“Seismic shifts in technology” could allow this Roberts wrote that the public was completely surveilled: and “we refuse to grant the government unrestricted access to these databases.”

But he called Carpenter’s decision “narrow” because it was based on weeks of surveillance data.

In dissent, four conservatives questioned how tracking someone’s driving violates their privacy. Security cameras and license plate readers are widely used by investigators and rarely questioned.

Lawyer Gen. D. John Sauer relies on this argument in defending Chatrie’s conviction. “An individual has no reasonable expectation of privacy in publicly visible actions,” he wrote.

The judges will make a decision by the end of June.
