A joint report by several branches of the United States intelligence community concludes “that racially or ethnically motivated violent extremists” are the “most likely to conduct mass-casualty” attacks against civilians. According to Al Jazeera, the report, concluded that “escalating support from persons in the United States or abroad, growing perceptions of government overreach related to legal or policy changes and disruptions, and high-profile attacks spurring follow-on attacks” could cause the threat of violence to increase in 2021 and beyond.
