The VIPs were not secured.
I did say
fairly quicky. For all I know, these cherry-picked moments of cops not actively fighting dozens of angry protesters came after the evacuations. And even if they didn't, I can still easily see cops making the snap decision to not start fights they couldn't possibly win. I can't say whether or not that was a sound tactical decision, but there's a world of difference between outnumbered cops not trying to fight protesters at a few given moments and the whole thing being a setup to make Trump supporters look bad.
After the Asley Babbit shooting the massive crowd of people in that wing turned back and left. There is well publicized video of this, taken from people within the crowd, which I am certain you are aware of. Stop LARPing. If there were people still in other distant wings after that, it is irrelevant to this demonstration that firearms worked to deter the crowd.
Okay, I looked up
a video of the Babbitt shooting. I wouldn't call this a "massive crowd" of protesters. A few of the protesters do seem to leave after the shot is fired. Plenty of them can clearly be seen still sticking around. Perhaps more importantly, we then see a team of cops with assault rifles bring up the rear, which I imagine played far more of a role in whatever deterrence happened in this scenario than the one lone cop firing his sidearm. In any case, your description of what happened is extremely disingenuous, and it's also extremely disingenuous to compare this one particular moment to the cherry-picked scenes of dozens of angry, screaming protesters marching past one or two isolated cops and say that, gee, all these outnumbered cops had to do was fire off a round and all these protesters would have quietly run home.
But ultimately, none of this matters. We all saw the violence of Jan. 6th. We all saw the angry mobs, we all heard their promises to murder anyone stopping Trump from getting a second term, we all saw them battering at the doors and smashing the windows while screaming for blood. None of these quibbles about whether or not this or that cop was actively fighting the protesters or whether or not this or that door was opened for them changes what we all saw and heard. These people were not at the Capitol to peacefully protest. They knew it, and we know it.
