This bill could have the potential effect of damaging someone's reputation, even though the student in question just made a dumb mistake. This is not to say they should forget what they did, but they deserve to be treated like everyone else. Opening criminal records would possibly change the perceptions of a student by his peers. They might look down on him and not give him the opportunities to interact and learn that they give everyone else. This bill would also notify parents of their child's criminal activity.
College is an exercise in independence to most students.
By informing a student's parents when he is charged with a DUI, feelings of distrust can be instilled in the parents. This could lead to parents pulling their children out of school. Also, it's not like students aren't punished when they break the law. They go to court just like everyone else, and they obey the same laws everyone else does. It just seems a little harsh to take punishment like this one step further and air someone's dirty laundry, especially when they may be trying to better themselves and learn from their mistakes.
