Evidence rule

This page is public-interest research. An argument grade is not a court finding. A watchdog page describes the device. It is not proof a Nevada agency bought it or turned a feature on. A product description is not a Nevada practice. Agencies are not merged: the City of Las Vegas Department of Public Safety, the Las Vegas Metropolitan Police Department, the Clark County School District, the City of Reno, and the Nevada Department of Public Safety stay separate. A hotlist hit is not a confirmed crime. Legal review of this page is unverified.

What it does

A national plate database pools reads from many cameras and many agencies so a search can ask where a plate was seen beyond one city. Private vendors and public networks both operate pools of this kind. A search of the pool is a different act from the camera that stored the plate.

Privacy watchdog concerns

Electronic Frontier Foundation. Automated License Plate Readers (ALPR). EFF says plate-reader cameras capture plates they see, with location, date, and time, and that stored history can reveal sensitive trips. EFF says the vast majority of scans are not connected to a crime at the moment of capture. This is EFF’s claim about the device. It is not a Nevada contract and not a court holding.

Constitutional issues

Unresolved question

Fourth Amendment, Nevada Constitution art. 1, § 18

Warrant practice not established for a Nevada agency

National LPR databases: No national-database contract is in this build. Carpenter does not decide a plate database. A vendor’s ability to host one is not proof a Nevada agency joined it.

United States v. Knotts, 460 U.S. 276 (1983). Counterauthority. United States Supreme Court. Public-road beeper tracking did not violate the Fourth Amendment on the facts of Knotts. A beeper case is not a holding about a plate-reader camera.
United States v. Jones, 565 U.S. 400 (2012). Analogical constitutional argument. United States Supreme Court. Jones held that attaching and using a GPS tracker was a search. Concurrences discuss long-term tracking. The mosaic theory is not a binding majority rule. Jones does not decide a plate reader.
Carpenter v. United States, 585 U.S. 296 (2018). Does not decide this technology. United States Supreme Court. Carpenter addressed historical cell-site location information. It does not decide an ALPR scan.

Statutes attached to read, not findings.

NRS Chapter 239. Nevada public-records law is the route to ask for contracts, policies, and logs. Citing it is not a finding that a surveillance practice is unlawful.
Nevada Constitution art. 1, § 18. State search-and-seizure provision. This page does not quote the section. No section anchor was verified. It is listed only where a search question is actually implicated.
42 U.S.C. § 1983. A civil remedy for a deprivation of federal rights under color of state law. It is not a warrant statute, and it does not itself make a surveillance practice unlawful.
