Jason Wilson in The Guardian:
The far-right Proud Boys group whom Donald Trump told to “stand by” during this week’s presidential debate is seen as a dangerous organization by law enforcement, according to leaked assessments of the organization from federal, state and local agencies. Trump’s refusal to condemn white supremacists during the debate, and his suggestion that the Proud Boys “stand by” during the current 2020 election campaign sent shockwaves through American politics. The Southern Poverty Law Center calls the Proud Boys a hate group. Files from the Blueleaks trove of leaked law enforcement documents reveal warnings that the Proud Boys, who some of the US agencies label as “white supremacists” and “extremists”, and others as a “gang”, show persistent concerns about the group’s menace to minority groups and even police officers, and its dissemination of dangerous conspiracy theories.
In a 22-page 2019 document titled Violent Extremism in Colorado: a Reference Guide for Law Enforcement, published by CIAC, the state’s Division of Homeland Security, and the Colorado Department of Public Safety, various incidents of violence involving the Proud Boys are discussed under the heading of White Supremacist Extremism. On page 15 of the document, the group is discussed in terms of the “threat to Colorado” from white supremacist extremists, and the “concern that white supremacist extremists will continue attacking members of the community who threaten their belief of Caucasian superiority”.
