During the 60s they were doing this, I remember one group ( I think a version of right wing) where the FBI plant won leadership of the group and started pushing it to become violent which the guys didn’t want to do but the plant pushed the idea, secured the illegal items, and basically ran the show of drawing the others into being something that they weren’t.
The right of Freedom of Association lies in ashes. We have an FBI for what good and worthy reason, exactly?
