The CIA has declassified nearly 700 pages of documents detailing scores of operations from the 1950s to 1970s. They include the illegal wiretapping of American journalists, extensive surveillance of civil rights and antiwar groups, bugging of political conventions, performing drug tests on U.S. citizens without consent, and plotting to assassinate world leaders. In 1960, the CIA enlisted two mobsters on the FBI’s most-wanted list in an attempt to assassinate Fidel Castro.
