P.S. And I agree that he should pay their way to Italy for the reading of the verdict and yes they should also be allowed to speak on their daughter's behalf, but that is just my opinion.
To that, I would say not only "no," but "Hell, no!"
In the U.S., they allow the family members of the victim to speak, but only during the sentencing phase after guilt has already been decided.
Not before.
Think about this: In Italy, as in the U.S., the standard for conviction on a murder charge is "proof of guilt beyond a reasonable doubt." If there's reasonable doubt of an accused's guilt, the task of the jury to acquit is clear. Now, if you have a mother and/or father of the victim, already convinced of the accused's guilt, speak before deliberations to give a tearful account of the pain they suffered and a plea not to make it worse by letting their child's killer(s) go free, you've changed the whole dynamic of the delibration. Instead of the prosecution having to show "proof of guilt beyond a reasonable doubt," you're essentially requiring the
defense to show "proof of
innocence beyond a reasonable doubt" -- because the jury members will be thinking that "if there's any doubt whatsoever that the accused may not be innocent, I can't possibly add to the pain of the family by letting someone who
might be guilty go free."
Letting the family of the victim address the court before a verdict of guilt or non-guilt is reached is an unbelievable perversion of the criminal judicial process -- far worse, IMHO, than anything the prosecution has done so far in the case. I'll go further and say that, if Hellmann has any control in the matter, and allows such an event to proceed, it will tell me with 100% certainty that he's already decided to convict.
