Fine, I won't get into it with you then. But that cop had plenty of room to retreat, he had no reasonable expectation of stopping that crowd by himself armed as he was. His life was not in danger.
Of course the cop could retreat, but it's his job to protect the people beyond the door. I would say it's reasonable for him to think his life is in danger, because people are trying to force their way past the door. I'm unsure of the timing of this, but if the cop is aware that a colleague is injured, then he has even more reason to fear for his life. And I can tell you for sure that if I was one of the protesters, and saw a cop with a gun in the vicinity of my presence, I would quickly fuck off somewhere else. So the cop can reasonable expect to stop this crowd, alone, with just one gun. It looks to me like he first fired a warning shot, and then fired at the protesters. When the woman slumped, they stopped trying to advance. So that cop did stop the crowd.

It's important that people notice how OBVIOUSLY dishonest the media is
I absolutely agree here. I've been banging on about media bias for many years, and it's only gotten worse in this time.
