Opinion: who was at fault for January 6 failures?

"If there was a security failure on January 6, and demonstrably there was, it was probably Nancy Pelosi's fault, and after looking at thousands of hours of footage, we came to the conclusion that many others have reached, which is the Capitol Police were not prepared for what happened, and that's fascinating when you think about it, because there was ample warning. The federal intel and law enforcement agencies knew perfectly well there could be a massive disturbance at the Capitol, but the frontline officers on duty that day didn't know and yet the people who kept that information from the frontline officers were overwhelmed by thousands of people milling around the Capitol building? The people who fell down on the job, who didn't do their job, they were not punished. They were rewarded, and you have to ask yourself, why is that? " Tucker Carlson, March 7, 2023 Fox News
