Warning : I am speaking to this exact case.
In American justice, per the constitution, you are only on trial for the specific charges. Meaning all past offenses are not on trial, as you presumably made restitution, or found not guilty.
I respectfully submit, that a fleeing subject is not a threat to a officers life, and does not warrant a death sentence from a officer, but instead is entitled to due process, under the law, regardless of any computer entry, regardless of the truth or falseness of said entry.
I believe, as most, in the right to defend one life, as a officer or civilian. In matters of life threating incidents, deadly defensive force is legal.
Furthermore, incompetent, liable, responsibility falls on said officer for mistaking her service weapon for her taser.
