The son clearly deserves a lot more time in jail. Not sure how much, but 6 months is beyond light. The dad is an idiot, but it's probably one of those "gotta defend the family" type of things. Still fucked up in this type of situation though. What comes to the guy after jail will at least be fair though, he will have an extremely difficult time finding a job, a place to live, and his reputation is forever ruined.
