Earlier quoted context omitted.
The Capitol Police were either incompetent or complicit. There are literally no other options. They knew there would be a big protests, numbers put it around 200k~300k (a tiny percentage of which actually went into the capitol building mind you). If they weren't prepared for this: incompetence. But there are videos of people getting selfies with guards, and staying within the velvet ropes when coming in. Something is…
They were understaffed, and it was clear that they could not protect both the building and the people. They correctly prioritized evacuating the people.
A police department with an intelligence unit couldn't guess that things might get a little out of hand when 3 weeks before, the President publicly used Twitter to ask his followers[1] to attend a "wild" protest on January 6th? Not that an intelligence unit was required as the plans were in the open. I have great difficulty in putting this down to incompetence, all things considered.
