Bad choices all the way around. First the shooter who started the whole thing by confronting the woman in the handicapped spot should have minded his own damn business. If you are that concerned about the handicap violation, get the license, take a picture, call the police and report it. There is no need to confront someone you don't even know over something that trivial. Then the father who confronted him pushed him rather forcefully. That constitutes assault and escalated the situation. At that point, nobody can say what the shooter was thinking in terms of fearing for his life. If the deceased was going to go that far, he should have reared back and cold-cocked the guy as hard as he could. He probably would have knocked him out and eliminated him as a threat. He might have claimed stand your ground based on the shooter being the aggressor and beat the assault charge. Finally, back to the shooter. Even though he was knocked to the ground, it does not appear that his life was in danger at the point where he fired. But you can't always count on a logical reaction in an emotional situation. All of this over a stupid handicap parking spot violation that was only going to last for about 5 minutes.
