"Your honor, I was in fear of my life.
His honor,"so, you shot him 7 times?"
Victim,"I wasn't counting. I just pulled the trigger until I was no longer in fear for my life."
End of discussion.
No matter where you are, being in fear of your life is the best reason to use lethal force. Just be sure you were, and can prove, you were in fear of your life. The location is secondary.
probably wouldnt hurt to add ‘I thought he was reaching for his waistband’...
