Although the House Jan. 6 committee has brought evidence of law enforcement’s carnage and failures in preventing and predicting the attack, little attention has been paid to those failures.

The failures behind the scenes have not been forgotten, sources tell NBC News. It is expected the committee will focus on the FBI’s and DHS’ intelligence and law enforcement failures, which left police unprepared for the mob that stormed the Capitol during a second round of public hearings in September. It is anticipated that these failures will be a key component of the committee’s final report on Jan. 6.

In a story shared by the online detective who worked for both the committee and the FBI, the FBI encountered a lot of challenges in its sprawling investigation of the Capitol attack, as well as why it failed to do more to prepare law enforcement before it happened.

A large file needed to be sent to the committee on Jan. 6, so the detective popped the files on Dropbox.

Special agents drove to the sleuth’s home to transfer files when the sleuth needed to give something to the FBI.

In June and July, the committee presented more information about Trump’s actions before and during the Capitol attack due to late-breaking revelations. As NBC News reported back in January, there is a lot of information that has been left on the cutting room floor, such as new information gathered by the “blue team.”

The investigators are solely focused on assessing law enforcement, intelligence agencies, and military preparedness and response, an aide to the committee told NBC News last week.

As a result, the team interviewed and deposed more than 100 witnesses and officials across federal and local agencies, including the FBI, Homeland Security, Fusion Centers and Office of Intelligence and Analysis.
