Even though by the time the hearing commences, the judge has already usually decided on the sentence, every competent criminal defence lawyer will advise their client to grovel and beg for mercy at the sentencing for two reasons:
- Acting recalcitrant could upset the judge and result in a heavier sentence than the judge originally planned because they feel a need to make an example of the defendant.
- Not being apologetic damages your future chances of parole when the parole board looks at the tape or record of the sentencing.
There’s also the possibility of appeals to get the sentence reduced. And the defendant’s family can apply for pardons. Pardons and commutations are usually associated with political grift in the US (and this is a well-deserved reputation), but they can also be applied for and governors occasionally grant them to prisoners who demonstrate they’re reformed even when they’re not otherwise eligible for parole.
Grovelling before the judge and acting like you accept you are guilty for sixty minutes costs nothing on the part of the defendant anyway.
