CHP officer convicted of killing husband in Compton

So this CHP officer kills her husband. She tells the cops she shot him in self defense. He was driving the car, she was apparently in the passenger seat and she said, "he became verbally and physically abusive," and she shot him in self defense.
First, they were coming from eating at a restaurant - Why did she have a gun? Sound familiar? Robert Blake.
Second, he was driving the car, how abusive could he have been while driving? AWD
I'm not disputing his being abusive at some point or maybe even all of their marriage, I don't know, he ain't here to defend that, however, I do know it ain't a whole lot I can do while driving, let alone beat somebody's butt to the point they get so mad and shoot me.
What did they talk about at dinner to where she seems to have gone from 0 to 60 in a second and shot the man to death. Her husband. The father of her children. Yes, unfortunately they had a 4-year-old and a teenager. Now they are parent less, because of her lack of planning. Let's see: Divorce, counseling, separation, restraining order, have him arrested. Surely she knew this, she's a cop. I mean she was a cop. Now she's a convict, a felon. WOW. 
Now, the judge convicted her and she faces some serious decades in prison. But, after hearing the verdict, she fainted. Really? What happened to the hardcore cop chick who locked and loaded and shot her husband in the head while he was driving them home from dinner? Having worked as a cop for several years, did she really think she was going to get away with it? Did she think they wouldn't investigate and look into all the evidence. Really? Come on now, it's Compton, law enforcement would investigate a jaywalker in Compton if they crossed the street funny. Just kidding. :) Sad, Sad. A family is torn apart and these kids will suffer for a long time to come.
