As the 50th anniversary of the 1963 March on Washington approaches ... where Martin Luther King Jr gave his famous I have a dream" speech, it is important to recall the extent to which King was targeted by the government. The FBI operation against King is one of the most shameful episodes in the long history of our government's persecution of dissenters. In a heavily redacted, classified FBI memo dated 4 January 1956 - just a little more than a month after Rosa Parks was arrested for refusing to give up her seat on a bus to a white passenger - stated that an agent "had been assigned ... to find out all he could about Reverend Martin L King, colored minister in Montgomery and leader in the bus boycott to uncover all the derogatory information he could about King." [FBI] director, J Edgar Hoover ... was deploying the vast resources he controlled against any and all perceived critics of the United States. The far-reaching clandestine surveillance, infiltration and disruption operation Hoover ran was dubbed "COINTELPRO", for counterintelligence program. The FBI's COINTELPRO activities ... were thoroughly investigated in 1975 by the Church Committee, [which] reported that the FBI "conducted a sophisticated vigilante operation aimed squarely at preventing the exercise of first amendment rights of speech and association." Among COINTELPRO's perverse activities was an FBI effort to threaten Martin Luther King Jr with exposure of an alleged extramarital affair, including the suggestion, made by the FBI to King, that he avoid embarrassment by killing himself. Deeply concerned about the crackdown on dissent happening under Obama, scholar Cornel West ... wondered if [King] "would not be invited to the very march in his name."
