The FBI opened a domestic terrorism" investigation into a civil rights group in California, labeling the activists "extremists" after they protested against neo-Nazis in 2016. Federal authorities ran a surveillance operation on By Any Means Necessary (Bamn), spying on [the] group's movements in an inquiry that came after one of Bamn's members was stabbed at the white supremacist rally. The FBI's Bamn files reveal: The FBI investigated Bamn for potential "conspiracy" against the "rights" of the "Ku Klux Klan" and white supremacists. The FBI considered the KKK as victims and the leftist protesters as potential terror threats, and downplayed the threats of the Klan. The FBI ... cited Bamn's advocacy against "rape and sexual assault" and "police brutality" as evidence in the terrorism inquiry. The FBI's 46-page report ... presented an "astonishing" description of the KKK, said Mike German, a former FBI agent. The FBI launched its terrorism investigation and surveillance of Bamn after white supremacists armed with knives faced off with hundreds of counter-protesters, including Bamn activists, at a June 2016 neo-Nazi rally in Sacramento. Although numerous neo-Nazis were suspected of stabbing at least seven anti-fascists in the melee... the FBI chose to launch a inquiry into the activities of the leftwing protesters. California law enforcement subsequently worked with the neo-Nazis to identify counter-protesters, pursued charges against stabbing victims and other anti-fascists, and decided not to prosecute any men on the far-right for the stabbings. In a redacted October 2016 document, the FBI labeled its Bamn investigation a "DT [domestic terrorism] - ANARCHIST EXTREMISM" case.
