Sooo, your example seems to reference making a victim statement at a parole hearing? Correct me if I am wrong. And fwiw, sorry you and your father went through whatever it is that you went through.
There are most certainly a variety of laws in place across the country to protect victims rights and their ability to make victim impact statements when it comes to sentencing hearings and parole hearings
But, in MBs case, we are talking about a Krol hearing in the state of NJ, which concerns a current mental health evaluation for someone who was adjudicated NGRI when it came to a crime.
Maybe it would be interesting to look at victims rights legislation relevant to the state of NJ and see what that has to say about Krol hearings?
