Regarding the Capitol Riot, and the effort by Capitol Police to HELP in preparation for a potential problem, note that "....House Sergeant at Arms Paul Irving rebuffed the idea, arguing he was uncomfortable with the "optics"..."
You. You're the missing link. But, it IS a fact that the DC police, prior to the day of the riot and knowing in advance that there could be a Capitol breach (long before Trump spoke), asked the House Sergeant at Arms (a Democrat) if he wanted the National Guard. And, the Democrat said "no."
Oh, that's funny ! But you should not call him that since you only have a few posts. You have to be on the website for at least 10 years before you can say what you think on here, or they will call you out on it. So be very careful and only criticize new people.
Was that conveyed to you firsthand by the Sergeant at Arms or do you have a link to some source material you quoted?
Sounds like it was a police failure. Whether there was a motive or not is not mentioned. https://apnews.com/article/capitol-police-reject-federal-help-9c39a4ddef0ab60a48828a07e4d03380
