I find it unhelpful that you guys get carried away by the "10 year" aspect of the sentence. Unless you are learned Italian legal scholars, you are most likely not in a position to comment whether the sentence is out of line with Italian sentencing standards. That someone would get a one-year suspended jail sentence in your country for a certain crime does not necessarily mean that it must be the same anywhere else. I would see your point if a 16 times manslaughter "usually" results in a much more lenient sentence in Italy, but nobody has made this point so far (and probably lacks the knowledge to do so). Also nobody knows how sentencing works in cases of multiple convictions. It could just as well be that the sentences for each single case are added up, but not each single sentence will be served. So it might be time to get off the high horse until you have gotten some insight into Italian criminal law and its application by the courts - rather than jumping to conclusions by reading what papers write.
