The storming of the Capitol on Wednesday was a catastrophic failure of protective law enforcement, as rioters overran Capitol Police barricades and gained access to a building that a lot of police were supposed to be protecting. How did it happen? Who screwed up? And what can be done about it? Benjamin Wittes sat down with Fred Burton, the executive director of the Center for Protective Intelligence at Ontic and a former protective officer; Garrett Graff, a journalist who covers federal law enforcement and who wrote a book about continuity in government; and Lawfare's executive editor Susan Hennessey. They talked about how bad the failure was on the part of the Capitol Police, who is responsible for it, what can be done now to bring the perpetrators to justice and how we should think about changing security protocols on Capitol Hill going forward.
