FBI Director Admits Buying Location Data Without Warrants

The Loophole at the Heart of American Surveillance

In 2018, the Supreme Court ruled in Carpenter v. United States that the government must obtain a warrant before collecting cell phone location data from a carrier. It was widely seen as a landmark privacy ruling — an acknowledgment that the digital trails we leave behind reveal an intimate picture of our lives, and that the Fourth Amendment's protections extend to those trails.

But the ruling had a significant gap: it applied only to data obtained directly from carriers. Data purchased from commercial data brokers — companies that aggregate location information from apps, advertising networks, and device sensors — fell outside its scope. Law enforcement agencies immediately recognized the opportunity, and in the years since, the FBI, the Department of Homeland Security, the IRS, and other federal agencies have quietly built surveillance programs around this loophole.

At a Senate hearing last week, FBI Director Kash Patel made that practice official and public. Under oath, he confirmed that the bureau purchases commercially available location data. "We do purchase commercially available information that's consistent with the constitution and the laws under the Electronic Communications Privacy Act," Patel told senators, "and it has led to some valuable intelligence for us."

What Data Brokers Actually Sell

To understand why this matters, it helps to understand what commercial location data actually contains. Data brokers aggregate location information from the GPS chips in smartphones, primarily harvested by the apps we install — weather apps, games, retail loyalty programs — that request location permissions and then sell that data to intermediaries. Some of this data is nominally anonymized, but researchers have repeatedly demonstrated that anonymization is largely cosmetic: patterns of movement are so unique to individuals that re-identification is straightforward.

The resulting datasets can contain location pings with timestamps accurate to within a few meters, updated every few minutes, stretching back months or years. For a federal agency purchasing such data, the practical effect is nearly indistinguishable from continuous warrantless surveillance of an individual's physical location history — except that instead of going to a judge for approval, the agency simply makes a commercial purchase.

Patel's admission makes clear that the FBI views this as a legitimate practice. The legal reasoning is technically defensible under current precedent: data that has been voluntarily shared with a commercial third party falls under the third party doctrine, which holds that such information carries no reasonable expectation of privacy. Courts established this doctrine in an era of landlines and bank records; applying it to smartphone location data capable of tracking every movement of a person's daily life is a different proposition entirely.

The Political and Legislative Response

The Senate hearing drew sharp criticism from lawmakers on both sides of the aisle. Democratic Senator Ron Wyden called the practice "an outrageous end run around the Fourth Amendment," noting it was "particularly dangerous given the use of artificial intelligence to comb through massive amounts of private information." The AI dimension is significant: what might have once required a human analyst to examine months of location data can now be processed algorithmically at scale, enabling surveillance programs that were previously impractical due to resource constraints.

Republican Representative Warren Davidson joined a bipartisan coalition in reintroducing the Government Surveillance Reform Act, which would close the data broker loophole by requiring a warrant whenever law enforcement agencies purchase location data from commercial sources. "Advances in technology, from AI to the explosion of Americans' data available for purchase, have far outpaced the laws protecting Americans' privacy and civil liberties," Wyden said in support of the bill.

The bipartisan nature of the reform effort reflects a broader political realignment on surveillance issues. Libertarian-leaning conservatives have long been skeptical of expansive government surveillance, while progressives have focused on how such tools are deployed disproportionately against communities of color and political dissidents. The data broker loophole has become a shared concern because it represents a categorical erosion of warrant requirements rather than a targeted program with even notional judicial oversight.
