Some cops, right? Six of them, I think. Also, I recall a video of a woman being shot by a cop after being the first through a door. Not sure.

Seems like a bubble there.
Or perhaps instead of a bubble, as you say, they were exposed to both sides. But, in that case, the dissonance didn’t temper the violence.
