Over what? Their own safety? That would imply the civilian is attempting to maim or injure them, and the officer should just let them do it.
Sorry its perfectly reasonable for the police to have their safety as a priority when dealing with hostile civilians.
What you fail to realize, in this situation, is the ICE agent handled the situation completely wrong. Mind you, the procedures are there for exactly this situation - where the civilian is being uncooperative. And that's important to realize - she was being uncooperative! Not a person of interest they were seeking to arrest!
1. ICE approaching/standing in front of the car rather than approaching from the side (procedure and common sense).
2. Filming with his phone.
3. Drawing his gun rather than simply avoiding the car.
This agent basically did everything wrong - by the book - and it resulted in a civilian being killed.
In the courts - he'll get self defense - but an agent with that much experience really f*cked up over something so benign.
Pulling out his gun should have been the last thing on his mind GIVEN THE SITUATION. This woman was being a nusance.
And to pull the gun out when he thought he was going to get run over makes little sense - first instict should have been to get the hell out of the way if he thought he was in danger - not to fire at her, and then to fire additioanl shots after he was in the clear.
