Yeah he got off easy.
I'm shocked no ones brought it up yet, but why the hell was he "traveling at 100mph."
I understand that it was an accident and he'll have to live with what he did for the rest of his life, but considering the drinking I think he should get AT LEAST 4-5, and in most places 100mph and up is criminal speeding which is also a felony, maybe cali is different.
Still... imo would easily be called reckless endangerment, I can't see anything less the 6 years being fair, considering someone died.
We all know probation isnt s*** compared to prison time.
