One of my siblings is a hill staffer who was in the building that day, and I can assure you, that's now how it happened. I realise, however, that to those down a right wing media rabbit hole, there's not much factual persuasion that will make a difference.
While there's not such thing as completely unbiased information, Politifact (quoted below) is about as close to neutral as you can find:
But the viral, 14-second video clip that some are using to claim that officers willingly let rioters past barricades and into the Capitol is being misrepresented online, said journalist Marcus Diapola, who shot the video.
"They definitely didn't just open the barriers," Diapola told PolitiFact. "The pro-Trump rioters made a fist like they were going to punch the cops, which is why I started recording. Then (police) backed off the barricades.
"They were completely outnumbered," Diapola said. "There wouldn't have been any point in fighting."
Diapola said the video was taken around 2 p.m. near the northeast entrance of the Capitol and estimated that the officers were outnumbered "100 to 1," with only around 30 officers spread out between three entrances on that side of the Capitol, compared with thousands of protesters.
Another video, taken on the west end of the Capitol, shows rioters quickly overwhelming police barricades and eventually forcing the officers to retreat.
While we found no evidence that officers allowed the mob in willingly, the security breakdown that enabled rioters to breach the building is under intense scrutiny, and officials have said an investigation is imminent.
