Capitol Attack: Special Event Designations Could Have Been Requested for January 6, 2021, but Not All DHS Guidance is Clear [Revised August 09, 2021] [open pdf - 4MB]
From the Document: "In the months leading up to the attack on the U.S. Capitol on January 6, 2021, there were reported efforts to organize large groups of protestors to travel to Washington, D.C., to dispute the outcome of the 2020 presidential election. [...] Questions have been raised about the extent to which necessary steps were taken to adequately secure the Capitol Complex, and share intelligence information. [...] We have a body of work underway that examines the preparation, coordination, and response on January 6, that we will begin issuing over the next several months, (see appendix III for additional details). We were asked to review, among other things, coordination between federal and local entities for security and emergency support for events at the U.S. Capitol and surrounding areas on January 6, 2021[.]. Specifically, this report examines the extent to which federal, state, and local government entities requested an NSSE [National Special Security Event] or SEAR [Special Event Assessment Rating] designation for the planned events of January 6, 2021 to include: (1) the definition of an NSSE and its designation process; (2) the definition of SEAR and its designation process; (3) the characteristics of past NSSE and SEAR events; (4) the applicability of NSSE and SEAR designations to the events of January 6 and the extent to which they were considered; and, (5) why NSSE and SEAR designations were not considered for the events of January 6."
