WARNINGS, SECURITY & RESPONSE
What was known, who knew it, what action was taken, and what later oversight found.
The security story of January 6 cannot be reduced to a single warning, agency, request, or decision. Federal and congressional reviews identified threat information before January 6, gaps in processing and sharing that information, weaknesses in Capitol planning, complicated emergency-assistance procedures, and delays as agencies responded to a rapidly changing attack.

The structured J6-S record separates warnings, intelligence sharing, preparation, requests, authorization, mobilization, operational response, and later oversight—and connects those stages to the J6-E Evidence Ledger.
Accountability Framework
Six questions for every institution
Identify the warning, intelligence, tip, assessment, or observed condition.
Identify the office, agency, command level, or individual that received it.
Establish when the information became available.
Determine whether it was shared with operational partners and frontline personnel.
Document planning, staffing, equipment, requests, approvals, deployments, or inaction.
Separate contemporaneous decisions from conclusions reached by later investigations.
Possessing general threat information is not the same as possessing specific, actionable intelligence about exactly what would occur. This page therefore distinguishes warnings of possible violence from later knowledge of the attack as it actually unfolded.
Before January 6
The warning environment
Federal agencies identified potential violence
Later Government Accountability Office review found that all ten federal agencies it examined identified potential threats of violence before January 6. GAO also found that some agencies did not fully process or share critical information with partners responsible for security planning.
Online threats and calls for violence
Government reviews documented threatening online rhetoric before January 6, including discussions of violence against Congress and elected officials. The existence of such material raised warning signs, but the specificity, credibility, dissemination, and operational use of individual reports varied.
The FBI record requires a later-evidence distinction
A 2024 Department of Justice Inspector General review concluded that the FBI could have canvassed its field offices before January 6 for intelligence that might have assisted preparations. The same review reported that it did not identify potentially critical intelligence in the FBI's possession as of January 6 that had not been provided to, or was not otherwise known to, law-enforcement stakeholders.
Institution by Institution
Preparation, communication and response
Federal Bureau of Investigation
Reviews examined the FBI's handling of tips, intelligence reporting, field-office information and confidential human sources. Later DOJ Inspector General findings add important detail to earlier public accounts and should be read alongside Senate and GAO findings rather than substituted for them.
Department of Homeland Security
GAO found that DHS intelligence components had access to threat-related information but did not consistently process or share all relevant material. January 6 was also not designated as a National Special Security Event or Special Event Assessment Rating event, a decision and process later examined by oversight bodies.
United States Capitol Police
Congressional and GAO reviews found that Capitol Police possessed information indicating the possibility of violence, but planning did not fully reflect the potential for an extreme attack on the Capitol. Reviews also identified shortcomings in intelligence dissemination, operational planning, staffing, equipment and contingency preparation.
Governance and emergency authority
The Capitol Police operated within an oversight structure that complicated emergency assistance. Later reviews found that procedures for requesting outside help were insufficiently clear and recommended giving the Police Chief clearer authority to request National Guard assistance during emergencies.
Metropolitan Police and mutual aid
As the Capitol emergency escalated, Metropolitan Police and other outside agencies supplied substantial assistance. The response demonstrated both the importance of mutual-aid relationships and the need for clearer regional planning and communications before a crisis begins.
National Guard
Request → authority → mission → mobilization → deployment
The D.C. National Guard response must be understood through its unique command structure. Unlike a state's National Guard under a governor, the District of Columbia National Guard operates under federal authority. A request for assistance therefore did not itself place Guard personnel immediately at the Capitol.
Separate the time assistance was requested from the time authority was granted, the mission was defined, personnel were notified and equipped, units moved, and Guard members arrived at the Capitol. Collapsing those stages into a single “request” or “deployment” time can obscure what happened.
Bipartisan Senate investigators found that opaque processes and lack of emergency authority contributed to delay. They also found that because Guard forces had not been activated and staged in advance for a Capitol mission, the Department of Defense needed time during the attack to approve the request and gather, equip and instruct personnel.
A Separate Evidence File
The pipe bombs
Explosive devices discovered near the Republican National Committee and Democratic National Committee headquarters form a distinct investigative record. They should not be folded into other January 6 claims without evidence establishing a connection.
Because investigations and official findings can change, the pipe-bomb section should always display the latest verified official status, source date, and any later charging or court developments. Earlier descriptions should remain in the correction/history record rather than silently disappearing.
Where reviews converge
Broad areas of institutional failure
Different investigations have used different evidence sets and reached findings with different scopes, but several themes recur: threat information existed; important information was not always processed or shared effectively; Capitol planning underestimated the possibility of extreme violence; emergency-assistance procedures were unclear; and the multi-agency response faced command, communication and mobilization challenges.
Those broad findings do not resolve every disputed question. The purpose of this project is to show both the areas of substantial documentary agreement and the places where later evidence refined, complicated, or contradicted earlier public understanding.
Accountability begins with a disciplined question: what did the institution know at the time, and what did it do with that information?
