How do the videos show that? The earliest of the linked videos is labeled as taking place at 1:07. The mob was already unruly before that. By that time the rioters had already overrun three layers of police barriers and forced the police to retreat to the based of the capitol steps. Which is why the police called for emergency back-up - the mob had already broken through their perimeter.

I'm not sure what you think this shows. If you participate in a riot and overrun the police positions, they will call for back-up - and the back-up will use standard riot control tactics if the situation doesn't respond. Those riot control tactics - like tear gas - don't make people break into the U.S. Capitol.

Your opinion is just that, your opinion.

This is an eye witness account....

Stage 1:
Snip
When I arrived at the building, I was approximately 30′ from the front edge of the crowd.

“Location/Time: I was on the West-side of the building from 1pm to 4pm– from the beginning of the supposed mob attack, to well past the time when USAF veteran Ashli Babbitt was shot and killed by police inside the building. Many of the images shown by the media come from this side of the building.”
“The attached video was taken by me personally and documents the below description of what I witnessed.”

The police had an ideal defensive situation, as the Capitol building sits atop a 35’ vertical limestone wall. To access the Capitol building from my location, you first needed to enter the courtyard 35’ above.

The only route to the courtyard was through a single narrow stairwell.
The cops needed only to defend the stairwell from above to contain the crowd.
Instead of staying on the high ground, the police defied all tactical logic by going to ground level and directly engaging the peaceful crowd.

Then, without warning, police began firing flash/bang grenades, tear gas, and pepper spray into the crowd.
Prior to this attack the police made no attempt to communicate with the crowd; they did not declare “an unlawful assembly” or ask the crowd to leave—they simply attacked a peaceful crowd.
A tear gas canister struck me in the head, knocking my eyeglasses to the ground.”
