Either you were ambiguous in your questions about the video wrt the larger discussion, or I misunderstood. Based on your clarification today, I will modify my answer accordingly.
Full disclosure, I haven't watched any video of Jan 6 and haven't read any official reports or opinion pieces. My only exposure to the events are the discussions in this forum. What intrigued me in the past few days is the interplay between (potentially) exaggerated numbers of violence by some compared to an official report which quantified violence incidents. That report also gave description to many of the acts deemed violent.
If a video exists showing 6 people beating another, then one would have to admit the count of violent people exceeds more than 5. I am comfortable with that reality. I am also at peace at a total count of violent acts and violent people captured on video. Where I will disagree with the qualification of violence is the legal threshold (spitting, pushing, etc) and what I consider to be "real" violence (hitting, beating, etc). Is there a hundred of such acts which meet my standard? If so, great, let's be willing to objectively call it out.
I hope that provides the insight you are seeking. Happy to distill it down further if you want.
With all that shared, I will reserve judgement the context of what is seen in the video. I don't think that reservation is extraordinary considering how other videos of other events have been misleading.
Lastly, my most controversial opinion of the Jan 6 protesters and rioters is they did it the "right" way. If a group is unhappy with government, then rioters and proteters should attack and disrupt government institutions and government officials. I think that is a much better approach than destroying one's one residential and commercial community.
