I do not think that criminals who have been convicted and sentenced for their crime(s) should be allowed to appeal their sentence.

I don’t think it’s fair that those who have been found guilty, convicted and sentenced of a crime are allowed to appeal their sentence and have it shortened. The victims of those crimes have got to live with that forever, yet the individuals who have committed the crimes can sometimes be allowed to appeal their sentences. I think the sentences people are given should be the sentence that they serve until it’s completed.
