A jury I was on came to that exact conclusion. Some crimes require state of mind to be proven. In my case, a guy was at a bar and got kicked out. He went to his car and grabbed a gun and fired two shots. Ultimately the decision hanged on "did he fear for his life" when two bouncers rushed him in the parking lot.
He was probably guilty of the two counts of aggravated assault, but the prosecution never showed that it wasn't self defense, which is what Arizona required.
If he was able to get to his car and retrieve his gun and shoot at them, it seems very unlikely that the “two bouncers rushed him in the parking lot”. He could have just driven away. Much more likely he was angry about being kicked out and went back with his gun and then the “two bouncers rushed him”.
