Peter Gersten has been a Criminal Defense Trial Attorney in New York City for 25 years and is currently a trial attorney with the Navajo County Public Defenders Office in Northern Arizona. He was the former Director and General Counsel for Citizens Against UFO Secrecy (CAUS). In addition, he is popularly known as the UFO Lawyer and is the only attorney to successfully sue the US Government for UFO documents.

Lawyer Peter Gersten has been a well-known figure in UFOlogy at least since the 1970s. He filed suit against the CIA in U.S. District Court in 1977 for release of documents concerning UFOs. This resulted in over 900 pages of documents being released, although there was little in them that wasn't already known. There were 57 pages that were held back due to "national security" concerns. UFOlogists made a big stink about this, claiming it's proof of a government cover-up. However, the files were held back because they might allow other nations to gain information on U.S. capabilities in electronic and signals intelligence. For example, there was one document where the CIA listened in on a Cuban pilot discussing a UFO sighting. The problem wasn't the UFO sighting, it was that we didn't want the Cubans to know we'd been able to hear their pilots' conversations.
