I think pulling his gun, given what I saw, was unnecessary. You can see the ICE agent going for the door was being very aggressive. But, he didn't pull his gun.
This person wasn't doing something that required a drawn gun, IMO. In fact, I think your first reaction should be to simply avoid being hit by the car (if that is in fact your fear). But to pull a gun, don't see it.
Of course what I think and what passes in a court room are two differnt things lol
As Gal and I both pointed out, seeing how much experience this person has will be interesting.
Also if you watch the slowed down video, he did backup once he heard the wheel spin.
Additionally, maybe backing up more and stepping aside/getting the hell out of the way if he felt endangered was the more prudent way to go rather than fire RIGHT INTO THE WINDSHIELD.
This was not a suspect or person of interest.
