Recent court cases in the United States raise the question of the standard required when the police want to know exactly where you are, using your cell phone to track you down. The issue again raises the question of how new technologies can invade privacy rights, and how quantitative changes in the type and amounts of data collected and stored result in qualitative changes in privacy rights. These require a reexamination of even established laws of privacy and of probable cause.
