I think you have the right case. However you aren’t required to retreat from your home. Considering who prosecuted the case I’ll side with her.
Retreating wasn’t the issue.
And it wasn’t her house anyway.
There are numerous articles, court documents, and analysis by a self defense expert and attorney, along with follow up in the comment sections @ http://legalinsurrection.com/
While I agree with you about the prosecutor and judge, she had a really thin case for self defense.
