Legally speaking, this was a victim impact statement.
Convicted criminals have long had the common law right of allocution, where they can say anything they want directly to the judge before sentence is passed.
Starting a few decades ago, several states decided that the victims of crime should have a similar right to address the judge before sentencing. And so the victim impact statement was created.
It’s not evidence, and it’s not under oath, but it is allowed to influence the sentencing decision.
(Of course, victim impact statements are normally given by real victims).
Do you mean that the script was written by the family, and it was only “performed” by generative AI? That’s very interesting, and not something I heard anywhere else.
