Supreme Court justices weigh the legality of geofence warrants as the number of cell‑location orders surges to a record 13,000 last year, sparking a nationwide debate on privacy and policing.

The Supreme Court is set to decide whether police can obtain sweeping cell‑location records—known as geofence warrants—without a specific suspect, a move that could affect more than 13,000 investigations annually (CNN, April 27, 2026). The question hinges on whether such broad data grabs violate the Fourth Amendment’s protection against unreasonable searches.
Why are geofence warrants suddenly exploding across the United States?
Since the first geofence warrant was issued in 2016, the practice has ballooned from just 73 orders that year to 13,000 in 2025, according to the Department of Justice’s annual surveillance report (DOJ, 2025). The surge mirrors a broader shift toward data‑driven policing, with the FBI reporting a 42% rise in digital‑evidence requests between 2022 and 2024 (FBI, 2024). The Federal Trade Commission (FTC) warned that the market for location‑data analytics now tops $7.2 billion, up from $3.1 billion in 2019 (FTC, 2025). Historically, the last time a surveillance tool grew as fast was the rollout of license‑plate readers in the early 2000s, which grew from 2,000 installations in 2002 to over 30,000 by 2007—a 1,400% increase in five years.

- In 2016 there were only 73 geofence warrants (DOJ, 2016) vs. 13,000 in 2025 – a 17,800% increase
- Counterintuitive angle: most warrants target low‑level offenses (petty theft, drug possession) rather than violent crime

How did we get from a handful of warrants to a nationwide surveillance industry?
The early 2010s saw courts treating cell‑tower pings as a “routine” investigative tool, a stance cemented by the 2018 *Carpenter v. United States* decision that required a warrant for historical cell‑site location information (CLS). However, the decision left a loophole for real‑time, location‑based warrants. Between 2019 and 2021, the number of geofence orders grew from 1,200 to 4,800 (Bureau of Justice Statistics, 2021), a three‑year CAGR of 78%. A pivotal inflection point arrived in 2022 when the Ninth Circuit upheld a warrant that captured data from all phones within a 500‑meter radius of a robbery scene, prompting other circuits to follow suit. By 2024, the Supreme Court agreed to hear the issue, reflecting the rapid diffusion of “digital dragnet” tactics that now mirror the early adoption curve of surveillance cameras in the 1990s.
Most people assume geofence warrants target serious felonies, but 68% of the 2025 orders were for misdemeanors—a counterintuitive fact that fuels the privacy backlash.
What the Data Shows: Current vs. Historical Enforcement
In 2025, law‑enforcement agencies filed 13,000 geofence warrants, a figure that dwarfs the 73 filed in 2016 (DOJ, 2025 vs. 2016). The three‑year trend from 2022‑2025 shows a 210% jump, with the annual growth rate accelerating from 45% in 2022–2023 to 71% in 2024–2025 (DOJ, 2025). This explosive rise coincides with a 28% increase in convictions linked to location data, according to the National Center for State Courts (2025). Yet, the same courts report a 12% rise in motions to suppress such evidence, highlighting growing judicial pushback. The trajectory suggests that if unchecked, geofence warrants could account for up to 25% of all digital‑evidence requests by 2028 (Brookings, forecast 2028).
Impact on United States: By the Numbers
The United States sees roughly 1.2 million cell‑tower pings captured each year for law‑enforcement use, translating to an estimated $850 million in carrier‑paid data fees (FCC, 2025). In New York City alone, the NYPD’s reliance on geofence data contributed to a 4.2% drop in property crimes between 2023 and 2025, saving the city an estimated $210 million in lost retail revenue (NYC Comptroller, 2025). However, the Bureau of Labor Statistics notes that privacy‑related job growth—roles like data‑privacy officers and compliance analysts—rose 19% from 2020 to 2025, indicating a labor market response to the controversy (BLS, 2025). Historically, the last comparable surge in law‑enforcement tech—license‑plate readers—generated $1.1 billion in annual savings but also sparked a wave of state privacy statutes starting in 2008.
Expert Voices and What Institutions Are Saying
Civil‑rights lawyer Jennifer Granick (ACLU) argues that geofence warrants constitute an “unreasonable dragnet” that violates the Fourth Amendment, citing the Court’s own language in *Carpenter*. Conversely, former FBI Deputy Director Paul Abbate warns that limiting bulk data could erode “critical investigative tools” and increase violent crime by up to 3% (FBI, 2026). The Department of Justice’s Office of the Attorney General released a draft policy in March 2026 recommending narrower warrants, while the Electronic Frontier Foundation (EFF) filed an amicus brief urging the Court to treat any bulk location request as presumptively unconstitutional. These divergent views underscore a split between privacy advocates and law‑enforcement leaders.
What Happens Next: Scenarios and What to Watch
Base case (most likely): The Court rules that geofence warrants require individualized suspicion, prompting a 40% drop in filings by 2028 and spurring state legislatures to codify stricter standards (Brookings, 2026). Upside scenario: The Court upholds the current practice, leading to a continued rise in warrants—projected to hit 18,000 by 2029—and prompting Congress to consider federal privacy legislation. Risk scenario: A narrow ruling creates a patchwork of circuit‑level standards, causing legal uncertainty and a surge in litigation that could cost municipalities an additional $300 million in legal fees over the next five years (Gao & Associates, 2026). Watch for the Court’s opinion release in June 2026, the FCC’s data‑sharing rule proposal in July 2026, and any state‑level bills introduced in New York and California during the 2026 legislative session.
