Hearsay is allowed in sentencing statements, and Arizona allows those statements to be in a format of their choice.
It’s the phase of the process where the judge hears opinions on what he should sentence the culprit to, so none of it is evidence or treated as anything other than an emotive statement.
In this case, the sister made two statements: one in the form of a letter where she asked for the maximum sentence, and another in the form of this animation of her brother where she said that he wouldn’t want that and would ask for leniency.
It’s gross, but it’s not the miscarriage of justice that it seems like from first glance. It was accepted in the same way a poem titled “what my brother would say to you” would be.
I feel like I could be persuaded either way, but I lean towards allowing them during sentencing.
I don’t think “it’s an appeal to emotion” is a compelling argument in that context because it’s no longer about establishing truth like the trial is, but about determining punishment and restitution.
Justice isn’t just about the offender or society, it’s also indelibly tied to the victim. Giving them a voice for how they, as the wronged party, would see justice served seems important for it’s role in providing justice, not just the rote application of law.
Obviously you can’t just have the victim decide, but the judges entire job is to ensure fairness, often in the face of strong feelings and contentious circumstances.
Legitimately interested to hear why your opinion is what it is in more detail.
