Forget the under the influence. Killing someone for going 80 in a 35 should be enough to put you away for a while. It sucks, because I know a lot of good people who did similar dumb things at that age and didn't get caught, but that doesn't mean there shouldn't be punishment when the dumb decision results in tragedy. I actually know someone who had similar situation and went to prison for quite a while. He turned his life around and now goes around and gives talks about his experience.
