His attorneys claim he was framed by the FBI and New York police as part of a campaign to destroy the black liberation movement of the 1960s. Because the federal Freedom of Information Act wasn't law at that time, the FBI wasn't required to turn over information on its investigations when Mr. Ferguson appealed his conviction in the 1960s.

Yes
