I recall this article from a while back.They didn't “blame” them for anything, they rightly pointed out their role in the destruction of the black American community, they just left out specifically how the CIA did it using the Freemasons.
"A series of expose articles in the San Jose Mercury-News by reporter Gary Webb told tales of a drug triangle during the 1980s that linked CIA officials in Central America, a San Francisco drug ring and a Los Angeles drug dealer. According to the stories, the CIA and its operatives used crack cocaine--sold via the Los Angeles African-American community--to raise millions to support the agency's clandestine operations in Central America."
