When one has to deal with a convincted fellow's crime, especially in evangelism, in truth (ie. sex offense, child rape, etc.),
perhaps it is more impartial to treat him/her this way, especially when there's doubt on the verdict:
I know what others have said about you, the court, the judge, the jury, the news, the media, the people, I've heard their side of the story, now I want to hear the truth from you. This is not about appeal, if you were not guilty. If you said you did it, then I will treat it as your testimony, not the judgment of the crowd.
And then move on from that point of life.
