Defense attorney Rich McGee painted Holmes as a diligent security guard who got behind Villegas’ car to try to prevent him from driving away drunk. He said Villegas used his Saturn Ion as “a battering ram,” pushing Holmes out of his way by backing the car up and striking him. Holmes believed he was about to be run over as Villegas finished backing out of his parking spot, according to McGee.

Hmmm ... I don't think positioning yourself so that someone can't get away without going through you and then killing them when they try to leave anyway qualifies as self-defense. On the plus side, this argument usually works for the police, so I'd give him about a 50:50 chance of getting acquitted.
