Sorry, but for a prosecutor to just relentlessly appeal a not-guilty verdict is simply absurd. Give them enough bites at the apple and they can convict anyone they want to eventually. In watching parts of that trial I was appalled at what I saw of the Italian judicial system. Sure, we've got problems here too... but I saw nothing that impressed me that their system is interested in due process at all. Quite the opposite. I wouldn't expect perfection anywhere but I sure expected better.
It’s a mystery but if the prosecutor is convinced he should appeal it
