I am not really following the reasoning behind what some of you are saying. When someone becomes a police officer we expect them to deal with potentially dangerous situations without killing people. That is a part of the job, especially in high-crime areas. Whether the victim here did something stupid or not does not absolve the killer. I am not familiar enough with the legalities of Unintentional Manslaughter (legalities weren't part of the discussion here anyhow), but on the face of it this sounds like it fits the bill. Will all of those aspects mentioned be brought up in court as mitigating factors? If her attorney is worth anything then yes, but that doesn't change that she killed someone with no adequate justification.
