About 28 years if the prosecution recommendation is followed.
The intent was to kill a criminal she believed to be a threat to her in her own home. The intent was not to kill an innocent man in his own home.
Intent isn't always relevant. The police officer in Minneapolis intended to kill someone posing a threat to his and his partner's safety. The result was killing an innocent, unarmed woman who posed no threat. The consequence was a murder conviction. No accident in either case.
The difference here is that her intent wasn't criminal, her intent was to do something she believed was legal.
Well she really blew that one then.
Clearly.
