I always found the creep a bit sinister, even going back to when he was at his peak. The way he's howling he's been fitted up now, I rather suspect that apart from bunging the two kids families, he's probably greased a few other palms out there, and expected to walk away from this one, but with the glare of media publicity, they've had to give him some jail time.
3 years isn't enough, but I bet a Vietnamese prison is a bit different to the pathetic system here now.
