The Pentagon asked the Capitol whether the Capitol needed staff to be staffed by the National Guard three days before Trump supporters caused trouble in the Capitol.
On the 6th local time, when demonstrators were scattered in the Capitol, the leaders of the U.S. Department of Justice offered to provide FBI agents.
The report quoted senior defense officials and two people familiar with the matter as saying that Capitol Hill police refused their help twice.
The report also said that despite receiving a large number of warnings about the possibility of riots and the resources and time to prepare, the Capitol Hill police only planned to face an ordinary demonstration.
Reports said that in June 2020, law enforcement responded violently to protests near the White House, causing a great uproar. Since then, U.S. officials have deliberately avoided similar situations.
But as a result, the U.S. Capitol was captured on the 6th in front of the world.
Police officers of an experienced law enforcement agency with a huge operating budget to protect parliamentarians in high-level security incidents were defeated by protesters. Four protesters died, one of whom was shot dead in the building.
The report pointed out that the riots and out-of-control raised serious doubts about the safety of the Capitol in future events.
The behavior on the 6th also raised serious concerns about the treatment of mainly white Trump supporters who were allowed to wander in the building for hours, while blacks and other protesters who demonstrated for police brutality in 2020 faced stronger and more aggressive police action.
