White supremacist groups have infiltrated US law enforcement agencies in every region of the country over the last two decades. In a timely new analysis, Michael German, a former FBI special agent who has written extensively on the ways that US law enforcement have failed to respond to far-right domestic terror threats, concludes that US law enforcement officials have been tied to racist militant activities in more than a dozen states since 2000, and hundreds of police officers have been caught posting racist and bigoted social media content. Police links to militias and white supremacist groups have been uncovered in states including Alabama, California, Connecticut, Florida, Illinois, Louisiana, Michigan, Nebraska, Oklahoma, Oregon, Texas, Virginia, Washington and West Virginia. Police in Sacramento, California, in 2018 worked with neo-Nazis to pursue charges against anti-racist activists. This week, police in Kenosha, Wisconsin, faced intense scrutiny over their response to armed white men and militia groups gathered in the city amid demonstrations by Black Lives Matter activists and others over the police shooting of Jacob Blake. Kyle Rittenhouse, a 17-year-old who appeared to consider himself a militia member ... was arrested on suspicion of murder after the fatal shooting of two protesters. Activists in Kenosha say police there have responded aggressively and violently to Black Lives Matter demonstrators, while doing little to stop armed white vigilantes.
