On January 6, 2021, the nation watched in horror as a violent mob stormed the United States Capitol building. It was an unprecedented attack on our democracy and its devastating consequences are still reverberating throughout our country. In the days that followed, it has become clear that prior to this tragic event, several federal agencies identified credible threats leading up to the MAGA I and MAGA II demonstrations in Washington D.C., yet many questions remain about how those threats were assessed and responded to. The General Accounting Office (GAO) report 'Capitol Attack' dives deep into these questions using open source data and related threat products to investigate what went wrong. Their findings show a complex web of intelligence gathering from multiple teams that was considered by some personnel but not acted upon until it was too late. With clarity borne from unwavering dedication to uncovering the truth - no matter how inconvenient or uncomfortable - GAO's careful analysis shines a light on weaknesses in both communication infrastructure as well as internal processes used for threat assessment at federal agencies spanning multiple administrations. This outstanding work serves not only to unearth lessons learned through tragedy but also demonstrates best practices academics, practitioners, business owners can leverage moving forward when investigating risk scenarios coming from any originator: foreign actors or groups sparked by social media platform manipulation of citizens right here at home. Capitol Attack should be required reading for anyone who places importance on security operations ¿Äì including national security experts, heads of state departments/agencies domestic safety organizations small business owners ¿Äì so they may better understand how they can protect themselves against future attack attempts while avoiding senseless loss of life.
