>He pulled his gun out before she moved the car anywhere
So this is a lie, by your own admission. Her car is already moving before he reaches for his gun.

The tactic of relocating is not a legal requirement. Failing to retreat doesn't prevent him from defending himself.
While Minnesota absurdly has "duty to retreat" laws, since he is operating as federal law enforcement he is only required to have "reasonable belief that the subject of such force poses an imminent danger of death... to the officer", and he can reasonably believe that she is trying to run him over, given she puts it in gear and pulls forward towards him, from a stop, as he's right at her bumper.
I think this is a strong case of a story having her side, his side, and the truth.
I think the reasonable position to take is that she was not intending to run him over, but he believed (reasonably) that she was, and so shot.
In this case, it'd be wrong to accuse Ross of murder, but it'd also be wrong to label Good as a domestic terrorist as Trump and his administration have been doing.
The administration, as usual, is making exaggerated and bombastic claims to support a base position that’s actually pretty reasonable (driving towards law enforcement to flee an interaction is dangerous for the driver and LEOs).
So this is a lie, by your own admission. Her car is already moving before he reaches for his gun.
