In 1975, he was appointed Special Deputy Attorney General to probe into the aftermath of the Attica Prison riot in 1971. His principal task was to evaluate a charge that crimes alleged to have been committed by law enforcement officers during the siege were later covered up by the State. In December 1975, after an eight-month inquiry, Meyer released the first volume of his findings, a 570-page document that came to be known as the "Meyer Report". The report concluded that, despite "serious errors in judgment," there had been "no intentional cover-up" by the prosecution.
