Dwalin2011 from tangentopoli to now members of high society was arrested and made time in jail; again if the public opinion is against a member of high society or a white collar men,the judge can dare but in the other cases they had much trouble to touch an untouchables.
Yes, but the Tangentopoli trials were about corruption, fraud, stealing public money etc. Sometimes they do jail time for that. But nobody dares to link a big white collar (especially politician) to
murder. Giulio Andreotti got close once, getting 24 years for the Pecorelli murder, but then it was reversed by the supreme court. And, even if it got upheld, he would have gotten house arrest immediately, probably in less than a week.
