because the court gets too backed up. thats what they do for more major offenses as well...plea bargain. (i'm a law student, haha)
Yup. That's pretty much it. they get you to plea guilty to a lesser penalty so that they don't have to go through the whole process of a court battle and there is a chance that something the state has to prove they won't be able to. For example if the officers radar license is expired. I thought it was interesting though most people probably won't. lol
