Yeah it is ******* riduclous. From what I can tell, in Australia a 'regular person' could face up to 10 years imprisonment for something similar.
I'm not sure if it's true but I read that he also paid a total of 500k Euros to the family of the victim which also mitigated the punishment. But what's that to him? **** all.
That payment might have been from a civil court case payout, or Spanish equivalent. Still, it's nothing much really. Like in many of these situations, the victim's family would probably trade back every last cent just to have their loved one back.
