You haven't seen a good portion of it yourself? I was assuming you had. Or are just pretending you're ignorant? I've already told you how that one video fits into context of the rest from my point of view, when you find the time to sus through the footage yourself (find your balls) come share what it looks like from yours.
Depends on the situation. If people are flooding in other parts of the building and units in those parts are retreating they could find themselves cut off and surrounded by rioters.
The Capitol police absolutely should of been more prepared for trouble that day. We could all see it coming a mile off. But I actually commend them for how they handled it once it did get out of hand. They shouldn't of started shooting, they shouldn't of escalated, it's how they should deal with all riots. Contain the most violent elements and let it runs its course.
