Can police point a thermal camera at your house and use it as evidence — without a warrant? That's exactly what happened in Kyllo v. United States, one of the most important Fourth Amendment cases of the modern era. In this video, we break down the facts, the Supreme Court's 5-4 decision, and why this 2001 case still shapes how courts handle GPS trackers, cell phone data, and other surveillance tech today.

📌 CASE CITATION: Kyllo v. United States, 533 U.S. 27 (2001)

In this video you'll learn:
✅ What thermal imaging is and how the DEA used it to investigate a marijuana grow house
✅ The Fourth Amendment "search" standard and how Kyllo changed it
✅ Justice Scalia's majority opinion and the "sense-enhancing technology" rule
✅ Justice Stevens' dissent and the "off-the-wall vs. through-the-wall" argument
✅ How Kyllo connects to later cases like United States v. Jones (GPS tracking) and Carpenter v. United States (cell-site location data)
