Nevada state police now hold the power to shadow your smartphone’s every move. No judge. No probable cause. Just a $12,000 annual contract slipped through with federal grant money. The Nevada Department of Public Safety inked the deal with Fog Data Science back in January, granting investigators access to Fog Reveal, a platform that hoovers up location pings from apps like weather checkers or navigation tools. Devices get tracked in near real-time. Patterns emerge—where you sleep, work, pray, protest. All without a knock on a magistrate’s door.
The contract caps at more than 250 queries monthly. Punch in a device’s advertising ID, and out spills a trail of breadcrumbs: homes, offices, haunts. Or flip it—scan an area for every phone that pinged there, then reverse-engineer lives from the dots. The Nevada Independent broke the story on April 10, revealing how this low-key purchase dodged the governor’s desk, secretary of state, and attorney general. Funded by a federal homeland security grant, it needed only a clerk’s nod. Boom. Surveillance unlocked.
Fog insists the data stays anonymous, tied to gadgets not names. Chief Privacy Officer Mark McGinnis told reporters, “Fog Data Science provides access to lawfully obtained, commercially and ethically sourced mobile advertising data that is anonymized and does not include personally identifiable information.” Users can opt out via a web form on Fog’s site. But privacy watchdogs scoff. Once data floods broker networks, opting out feels like closing the barn door after the horses bolt. And those 250 queries? Researcher Beryl Lipton at the Electronic Frontier Foundation warned, “You can cover a lot of ground with 250 queries. One of the big concerns is that law enforcement would be able to vacuum up or have access to information about people who are nowhere near involved with anything that they’re investigating.” EFF’s 2022 probe exposed Fog Reveal’s reach: billions of pings from 250 million devices, sold cheap to small-town sheriffs.
This isn’t Nevada’s first dance with phone spying. Back in 2013, Las Vegas Metro cops grabbed cell-site simulators—Stingrays—that mimic towers, slurping signals from blocks at a time, even snagging texts in some setups. Details? Still classified. Then 2020: California cops tower-dumped data on a Nevada murder suspect, spilling info on 1,600 innocents. A federal judge in Nevada ruled it unconstitutional—a general warrant forbidden by the Fourth Amendment—but let the evidence stand under good-faith exception. Echoes of Carpenter v. United States, the 2018 Supreme Court smackdown demanding warrants for carrier-held historical location data. Yet here’s the loophole: Buy from brokers, skip the courthouse. It’s commercial doctrine on steroids, rooted in a 1979 ruling that what you share with third parties holds no privacy shield.
Department spokespeople stay tight-lipped on apps targeted or exact tactics, citing operational security. They promise internal controls: “use of the product follows agency procedures and internal controls for computer access, confidentiality of information and case management.” Post-story clarification: No traffic stops. No mass fishing. Limited to trained analysts at the Nevada Threat Analysis Center for crimes or threats. Still, Jacob Valentine of the ACLU of Nevada calls it “alarming.” “I think there’s more and more attempts to track where we are at all times and circumvent the warrant process,” he said. Clark County public defender John Piro goes further: “Just because you choose to navigate with an app like Waze doesn’t mean you consent to the government being able to see all of your movements.” Unconstitutional, he argues. Everyone a suspect.
Zoom out. Fog Reveal thrives nationwide. Missouri highway patrol zeroed in on puppy-breeding sites. Arkansas prosecutors tapped it sans warrant in emergencies. North Carolina’s Rockingham County sheriff ponied up $9,000 yearly. AP’s 2022 reporting tallied dozens of agencies. EFF docs show pricing: base $6,000-$9,000, extras for queries. Cash-strapped departments love it—Nevada’s included, amid trooper shortages and counterterrorism duties. Other states boast solves: murders, even Jan. 6 leads. But Lipton flags protester tracking: Query a rally zone, trace pings home. No audits? Abuse beckons.
Nevada’s surveillance web thickens. Every major city runs Flock Safety license plate readers, unregulated despite lawmaker gripes. AG Aaron Ford in March urged Congress to rein in data brokers. Yet here comes Fog, quiet as a shadow. Slashdot amplified the buzz on April 19, linking back to Nevada Independent via its roundup. X chatter erupts—posts decry the loophole, from Citizen Lab’s John Scott-Railton exposing Webloc tools to Naomi Brockwell mapping third-party doctrine pitfalls.
So. Turn off location services? Ditch apps? Faraday bags kill usability. Opt out helps, maybe. But data’s everywhere—ads fund free apps, brokers feast. States stir: Some eye warrant mandates for bought data. Nevada? Chronic understaffing meets terror threats. Public safety pitch sells. Privacy erodes one query at a time. Investigators gain eyes everywhere. Citizens? Invisible threads bind your steps. Watch your pings.
