Doesn't the judge have to give him a prison sentence to begin with so there is something to apply if he violates his probation? The sentence was rehab and probation. No prison time, suspended or otherwise. If he violates his probation under his current sentence then they can't impose a prison sentence that doesn't exist. They would have to arrest him, charge him, try him, and convict him before they can put him in prison, wouldn't they? Just another chance for his lawyers to work out a plea based on his upbringing.
Well, look at it this way; any prospective employer will end up looking this up and frankly finding out that he got away with murder because of citing “Affluenza” and this will be a blot on the social life of his parents and a stain on their family name as well. He won’t get away with it when he face St. Peter at the pearly gates and face his victims and then there is the civil suit.
In so many ways, a nightmare is just beginning.
