A video published Monday by the Center for Investigative Reporting reveals that the man responsible for arming and training members of the Black Panther Party in the 1960s did so while acting as a federal informant. According to reporter Seth Rosenfeld, Richard Aoki was approached by FBI agent Burney Threadgill Jr. in the late 1950s, around the time he was graduating high school, and developed into a source into the activities of various political groups during the following decade. “I said, ‘Well, why don’t you just go to some of the meetings and tell me who’s there and what they talked about?’” Threadgill is quoted as saying. “Very pleasant little guy. He always wore dark glasses.” Aoki, who committed suicide in 2009 after working as an educator for 25 years following his involvement with the party, has been remembered for his activism. He was the subject of the biography Samurai Among Panthers: On Race, Resistance And A Pardoxical Life, which traced his ascent within the organization, where he became the highest-ranking non-black member of the party.
