Are you suggesting someone intentionally worded the report to make it sound like the woman was shot by the police, knowing that wasn't the case? Is there any evidence of that?
And how do you know that it wasn't a round from the trooper's gun that killed her?
Here is a link to the statement from the police and the relevant portion (bold emphasis mine):
Kentucky State Police
After the vehicle came to rest on the ramp, the trooper attempted to apprehend the suspect.
While attempting to apprehend the suspect the trooper heard a gunshot coming from within the vehicle which he perceived as an immediate deadly threat to himself and the female passenger. The trooper drew his service weapon and fired at which time the suspect was struck resulting in his death at the scene. During this event, the female passenger was struck by at least one round of gunfire. The female was transported by Oldham County EMS to the University of Louisville Hospital where she was pronounced deceased by the Jefferson County Coroner.
The statement does not state whose gunfire struck the female passenger. It remains possible that it was a round from the police.
Several lessons that should be kept in mind:
(1) Avoid a rush to judgment.
(2) Initial reporting of an event often contains inaccuracies, including because those at the scene may make mistakes, information directly from the scene is going through multiple levels and there's a chance that each person's hearing and interpretation distorts the original, people are relying on "sources" that don't really know, speculation is being mixed in, assumptions are being made, the choice of words is not great, etc.
(3) When reading media reports, remember that the writers may be using words that different from original sources. And when reading message board posts about a media report, remember that you're getting the poster's interpretation. If possible, always work back to the original source to avoid the whisper down the lane/telephone game effect.
(4) Read the original sources and media reports closely, and don't add in things that aren't there, such as a source of the round that struck the passenger.
If the statement is accurately stating what the trooper said, and the trooper is accurately recalling that he heard a gun shot, it's certainly possible that the driver shot the passenger. But note that "gunshot" is singular, whereas "drew his service weapon and fired" could mean the trooper's weapon was fired once or more than once. We don't yet know know how many times the trooper shot his weapon. So it's also possible that the trooper hit the passenger. Note also that it says the passenger "was struck by at least one round of gunfire." So we don't even know yet how many rounds struck her.
