The Washington Post just reported that the FBI had advance warning of the violence on January 6 from one of its offices in Norfolk, Virginia.

A day before rioters stormed Congress, an FBI office in Virginia issued an explicit internal warning that extremists were preparing to travel to Washington to commit violence and “war,” according to an internal document reviewed by The Washington Post that contradicts a senior official’s declaration the bureau had no intelligence indicating anyone at last week’s pro-Trump protest planned to do harm.

A situational information report approved for release the day before the U.S. Capitol riot painted a dire portrait of dangerous plans, including individuals sharing a map of the complex’s tunnels, and possible rally points for would-be conspirators to meet up in Kentucky, Pennsylvania, Massachusetts and South Carolina and head in groups to Washington.

“As of 5 January 2021, FBI Norfolk received information indicating calls for violence in response to ‘unlawful lockdowns’ to begin on 6 January 2021 in Washington. D.C.,” the document says. “An online thread discussed specific calls for violence to include stating ‘Be ready to fight. Congress needs to hear glass breaking, doors being kicked in, and blood from their BLM and Pantifa slave soldiers being spilled. Get violent. Stop calling this a march, or rally, or a protest. Go there ready for war. We get our President or we die. NOTHING else will achieve this goal.”

BLM is likely a reference to the Black Lives Matter movement for racial justice. Pantifa is a derogatory term for antifa, a far-left anti-fascist movement whose adherents sometimes engage in violent clashes with right-wing extremists.

Yet even with that information in hand, the report’s unidentified author expressed concern that the FBI might be encroaching on free speech rights.

The warning is the starkest evidence yet of the sizable intelligence failure that preceded the mayhem, which claimed the lives of five people, although one law enforcement official, speaking on the condition of anonymity to avoid disciplinary action, said the failure was not one of intelligence but of acting on the intelligence.

An FBI official familiar with the document said that within 45 minutes of learning about the alarming online conversation, the Norfolk FBI office wrote the report and shared it with others within the bureau. It was not immediately clear how many law enforcement agencies outside the FBI were told, but the information was briefed to FBI officials at the bureau’s Washington field office the day before the attack, this official said.
