Declassified: John Lennon

John Kerry and Martin Luther King Jr. both made the list, but so did one very famous Brit--John Lennon. From 1956 to 1971, the FBI reacted to social changes such as the Civil Rights Movement with a sweeping counter intelligence program, inelegantly dubbed COINTELPRO. Using information obtained under the Freedom of Information Act, this program details how John, his family and his friends were affected by the FBI's attentions.
