The lawyer for the shooter is full of it. She was akwardly stuck in the window and could have been easily taken into custody. There us no way she could have used deadly force even if she were armed in her position. Police were right there next to her and could have arrested her easily.
He could have fired a warning shot.
If she were St. Floyd, this guy would be toast. But not so. If you watch the tape, he actually panned about from his right to left to seek her out for the kill shot. May not stand for a first degree but second degree, absolutely.
Remember this, she was NOT armed and posed not a great threat.
