I'm speculating where her attention is based on the video. Why would she be looking towards the officer on her right when it's the 2 officers on the left that she was currently engaging with. I mean, I guess if any kind of federal agent steps out onto a road, then any cars would be accelerating towards them....that would probably be enough justification for you guys in any situation.
She was clearly trying to escape. Do you truly believe that her actions of reversing before turning her wheel to the right was so that she could try to run over the ICE agent to her right? It clearly looks as though her actions were done with the intention of driving off down that road away from the ICE agents.
