Oh vey. Yes, that's what one wants out of a prosecutor. Being kind and polite. During the trial in 2009, Mignini was neither kind nor polite.
So, maybe citing some facts might put this all in perspective. Mignini STILL insists that Knox and Sollecito were on site during the murders. That is neither kind nor polite. Between Knox and he, they have agreed to at least regard each other as human beings - Knox, especially, not wanting to fall into the trap of demonizing opponents, and devaluing their humanity. She'd had enough experience with people doing that to her.
Still, the facts are these.... the acquiting court, the 2015 Supreme Court Panel was clear.... they entertained that EVEN IF Knox and Sollecito had been at the cottage at the time of the murder, the lack of ANY reliable evidence of either of them in the murder room made the whole thing moot.
In my view, Mignini showed cracks in his own thinking about the murder, showed it in the Netflix documentary. In it, he gave copious and first hand accounting of his own thinking to do with the crime. Towards the end, he, too, entertained the possibility that he might be mistaken, and if so, hoped he could get forgiveness.... or some such thing.
That's not him being kind and polite. That is a man struggling with his own conscience in ruining the lives of two people - and de facto lying to the victim's family as to the manner of their loved one's death.
Meanwhile, Rudy Guede faces new charges for violence against women. That one is a fact.
