Take it down a notch.
That's the nature of code law, which is just as "first world" as common law.
There are aspects of common law that code jurisdictions also consider strange or backward - like prosecution in absentia.
And there are specific American practices - like allowing attorneys to coach witnesses before they testify - that are considered beyond the pale by foreigners, both common law and code.
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.
