That’s just not true; look up NJ’s DUI laws. It isn’t even a misdemeanor; it is a traffic violation. Perps are not entitled to pre-trial intervention or a trial by jury (because it isn’t a crime) and it can’t be expunged for the same reason.
You’re right about NJ, I thought all States had changed their laws. However in NY (where Deblasio is talking about) it is a misdemeanor.
