Daniel became a government transparency advocate after U.S. law enforcement used a secret cell phone surveillance device to locate him inside his home. The device, often called a “Stingray,” simulates a service provider cell tower and tricks cell phones into connecting to a law enforcement controlled signal that identifies, locates, and in some cases, collects the communications content of cell phones.

Before Daniel brought Stingray cell phone surveillance hhh into the public spotlight in 2011, law enforcement concealed use of the device from judges, defense attorneys and defendants, and would typically not obtain a proper warrant before deploying a Stingray.

In 2014, Daniel peeled away documents from government agencies that detail use of the Stingray and other cell phone surveillance. In a Freedom of Information Act lawsuit against the FBI, Daniel represented himself and successfully argued to have the FBI produce more documents and to remove redactions from previously disclosed documents.
