Congresswoman Bella Abzug infamously had issues with trusting CIA when it came to their handling evidence of illegal and improper Agency activities. Internal memos shows those fears were well-founded - while the Congresswoman fought to prevent the destruction of records of CIA wrongdoing, the Agency rushed to begin destroying everything they could.
One of the dilemmas of reading declassified documents is that readers are constantly faced with the question of whether or not to take the exemptions at face value - after all, CIA redacts beer brands and cafeteria names while claiming to “protect sources and methods.” Doing so erodes faith in the Agency’s choices to redact certain pieces of information, creating a situation where one of two possibilities are likely: that the CIA chose to improperly redact information to protect itself from embarrassment regarding improper activities, or that some of those activities are still seen as at least potentially valid.
In 1976 and again in 1977, the Justice Department decided not to prosecute anyone for the CIA’s illegal surveillance and mail openings. The report issued in 1977 reveals the Justice Department’s highly flawed reasons, including claims that prosecution would not serve to prevent such questionable or outright illegal surveillance from happening again - ironically setting the stage for modern surveillance programs.
