Yeah, it is bad, but let me be the devil's advocate: Italy's justice has three levels, and it's very easy to be judged guilty during the first step, the judge needs only a small evidence and he/she defers to the next level. Frankly, I don't feel the Italy's justice system to be worse than other countries, it's pretty fair IMHO (disclosure: I'm Italian but in no way related to Italian justice)
The phrase American defense lawyers use is “the process is the punishment.” Even if a higher tier eventually exonerates the wrongly accused, they’ve already been dragged through years of stress, had their reputation ruined, and probably have gone bankrupt.
Unfortunately the higher levels allow those currently invested in the system as is to say “see, they were exonerated” and ignore the massive amount of purposeful damage done in the process.
That was a first level sentence, which was revoked in 2015 https://www.sciencemag.org/news/2015/11/italy-s-supreme-cour...
