The U.S. Capitol Police has 1,800 men and women dedicated to protecting the people’s citadel. Since September 11, their numbers have swelled, their procedures have changed, their perimeters have expanded, and their preparedness for a persistent threat has been plain. But they have been fighting an old battle. International terrorism is no longer the major threat they face, and arguably, it has not been for years.
What is happening today is the result of this failure of imagination. Security officials may claim the threat posed by a mob of white vigilantes was too far out of mental reach—it was something they could conceive of but not calibrate their plans for. But that’s an indictment, not an excuse. It’s a failure of the Capitol Police’s own leadership, and a failure of the Department of Homeland Security, to take right-wing radical agitation seriously. It is also a consequence of prejudice, although we should not be too hasty to make assumptions about the racial sociology of a security agency like the Capitol Police that has such a specialized mission.
