Since judges are human beings, rather than any kind of true impartial force, the government lays down some advice on how sentences should look for different crimes. This is a way to make it so that someone charged with assault in one area does not get a much higher sentence than someone charged in a different area. The idea is that similar levels of crime receive similar sentences.
While judges have to adhere to some sentencing guidelines, the guidelines usually include a range of years to be served in prison or a range of fines. There are many provisions that can be used to help a defendant receive a lower sentence based on the specific situation. Getting the legal research needed to ask for this sentence can mean you’re out of jail a lot sooner.
