Which case involved the ruling on police use of GPS tracking devices?

The case that involved the ruling on police use of GPS tracking devices is indeed United States v. Jones. In this landmark decision, the Supreme Court held that the warrantless installation and monitoring of a GPS tracking device on a suspect's vehicle constitutes a search under the Fourth Amendment. The Court emphasized that this kind of surveillance extends over a long duration, thus infringing on the individual's reasonable expectation of privacy.

The ruling established that law enforcement agencies must obtain a warrant based on probable cause before using such technology to track individuals. This decision marked a significant point in the scope of privacy rights in relation to modern technology, highlighting the importance of judicial oversight in law enforcement practices.

In contrast, the other cases listed pertain to different issues of search and seizure, student rights, or DNA collection, and do not address the specific technicalities concerning GPS tracking by law enforcement. Thus, United States v. Jones stands out as the relevant case regarding GPS tracking devices.
