The Virtual Dragnet: Chatrie v. United States & Geofence Warrants

In the quarter-century since September 11, American policing transformed into a high-tech surveillance powerhouse—from military thermal imagers and GPS beacons to geofences and AI-powered cameras. But every time law enforcement rushes into an unregulated technological frontier, the Supreme Court has had to pull the reins. Today, as Flock license plate cameras map whole cities and police drones take to the skies, has technology finally outpaced the Constitution? In this episode of reWandt, we trace the post-9/11 evolution of law enforcement technology and the continuous constitutional tug-of-war between police power and civil liberties. We walk through the five landmark decisions where the Supreme Court intervened to protect citizens: Kyllo (thermal imaging), Jones (GPS tracking), Jardines (curtilage), Riley (cell phones), and Carpenter (cell-site location tracking). Then, we confront the two newest unregulated frontiers: Flock Safety's nationwide AI automated license plate reader (ALPR) cloud network and autonomous police drone fleets. Can 1980s public-road and airplane flyover cases justify a 2026 digital panopticon?

If the police secretly crawl beneath your car in the middle of the night and attach a magnetic GPS tracking beacon, have they violated your constitutional rights—and how did an 18th-century property rule written for horses and carriages reshape modern digital privacy? In 2004, federal agents investigating nightclub owner Antoine Jones covertly attached a GPS receiver to his Jeep and tracked his movements 24/7 for 28 continuous days. The surveillance yielded over 2,000 pages of tracking logs, leading to a stash house with 97 kilograms of cocaine and a life sentence. But because police violated the terms of their warrant, the case escalated to the Supreme Court. In this episode of reWandt, we deconstruct the landmark ruling United States v. Jones (565 U.S. 400). Explore how Justice Antonin Scalia stunned legal scholars by reviving 18th-century English common law trespass to rule that automobiles are protected 'effects.' We dissect Justice Samuel Alito's 'Mosaic Theory' of prolonged surveillance and Justice Sonia Sotomayor's prophetic concurrence attacking the Third-Party Doctrine. Finally, we examine the chilling reality of 2026: why police no longer need to touch your car when automakers and data brokers harvest your real-time vehicle telematics around the clock.

Can the government track your physical movements backward in time for months without a search warrant? In 2011, federal prosecutors investigating a series of retail armed robberies in Detroit obtained 127 days of historical cell-site location records for Timothy Carpenter—harvesting 12,898 distinct location points without a Fourth Amendment search warrant. Instead, the government relied on Section 2703(d) of the Stored Communications Act, arguing that under the traditional Third-Party Doctrine, cell phone users voluntarily disclose their location to wireless carriers simply by keeping a handset powered on. In this episode of reWandt, we unpack the landmark 2018 Supreme Court ruling Carpenter v. United States (585 U.S. 296). Explore how Chief Justice John Roberts and the high court rejected the mechanical application of 1970s landline telephone precedents to modern smartphones, why continuous cell-site tracking functions as a digital time machine, and how the Court established a bright-line warrant requirement that protects 300 million Americans from retrospective mass surveillance in everyday modern life.
