These are the only images I needed to see to form my opinion.
One ICE Officer is approaching her car and giving her lawful commands through her open driver’s side window. The car is in “Reverse” and her wheels are cut to the left. There is no ICE Officer to her front.
Here she has moved approximately 3 feet back as you can see from the relationship of her tires to the white line in both images. The ICE Officer to her front is still visible. In this image her “Reverse” white tail lights are off — she has shifted into drive. Her front tires are still cut to the left, and her front end has reoriented more towards the Officer now in the center of her front end.
This is as far backwards as she travels. Her brake lights are now off — she’s in “Drive” and her foot is no longer on the brake. The ICE Officer is now in front of her driver’s side headlight, and her wheels are facing straight ahead. At this moment her front wheels break traction as she attempts to accelerate forward. Had the tires not spun on the ice she would have made immediate and forceful contact.
Just a fraction of a second later you see the ICE Officer drawing his firearm — her wheels are still straight. That’s the moment he decided to use deadly force — he recognized at that moment the fact that she was about to run him over. He resorted to deadly force in self-defense and defense of others.
That’s it.
