Public-interest lawyers from the New York Civil Liberties Union and Cardozo School of Law have sued state corrections officials for allegedly banning a Pulitzer Prize-winning history of the 1971 Attica prison uprising at facilities across the New York.

The lawsuit, which accused the state Department of Corrections and Community Supervision of upholding an “objectionable” censorship regime, claimed that Heather Thompson’s book “Blood in the Water: The Attica Prison Uprising of 1971″ had been banned in state prisons since it hit bookshelves in 2016.
