He could have stepped aside instead of drawing his weapon and there wouldn't have been any issue. He also shouldn't have walked around the car that way, that was entirely unnecessary and dangerous.
The woman is clearly distracted by the other ICE officer, that's just an all around dangerous situation they created entirely unnecessarily.
He probably spent awhile in the hospital pondering what happened. He probably spent time talking to his ICE buddies. About his injuries. About using the taser. About how much he wished he had used his sidearm instead of his taser. And his buddies encouraging him. His buddies encouraging him, "next time don't be so kind with the tazer." He thought about what he would do "next time."
He was fantasizing about "punishing" the guy who dragged him. He fantasized about that for months. He "lost" the last fight and walked away with more injuries than the other guy. Got to even the score.
He evened the score. He won. And he will get away with it.
There is no Karma. He is victorious, and indeed, now placed upon the mantle by the administration as a hero who settled a score against "domestic terrorism."
>>> trig·ger-hap·py /ˈtriɡər ˌhapē/
[adjective] ready to react violently, especially by shooting, on the slightest provocation.
The officer chose to engage and close on the vehicle and chose to circle from the front. If the officer was concerned about being run over, they shouldn't have stood right at the bumper. The car was clearly in gear, moving forward was an obvious expectation.
Did the officer have an escape route? Obviously yes, since they only had to side step to avoid the car. Was there an exigent circumstance? No, the officer could have retreated and nobody else was clearly in harm's way. Was the driver clearly a threat? Again, no.
No, this was straight-up murder from a trigger happy psychopath.
If nothing else, I do hope that everyone involved gets the help and care they deserve. Post-trauma depression is a real thing and diagnosis is sketchy at best.
