While watching OJ's sentencing today, something crossed my mind. The attorney/s will give a plea for the client then the convicted person gets to essentially plead for their life or a short sentence. The judge patiently listened to all the attorneys as well as the convicted guys. Then she gave out the sentences.
My question. Does a judge ever change his/her mind about what the sentence will be based on the pleas from the attorneys & convicted or the victims and their families?
If not, then why allow the begging or the victim's impact statement?
