In that case, help me edit it for tone.
What I wish to point out is that no matter how heinous the crime of which he stands accused, he is not yet a convict, and he enjoys a right to a fair trial according to the legal system of the nation that is trying him. Add to that the idea that a fair trial may find that the cold case leaves insufficient evidence to convict, or that he was of diminished responsibility on account of youth and duress.
I wish to reject as irrelevant the argument that the benefit of law should be denied to this defendant because it has been denied to others. That is an attack on the speaker as hypocritical, without addressing the merits of the argument. How does denying a fair trial in this particular case advance the rights of those others?
I doubt that there is any tone in which these statements could be cast that would not come across as condescending.
