if you get it renewed and take it to court the judge will probably throw it out since it was only expired for 30 minutes. did your b-day fall on sunday or on a regular business day? if it fell on sunday then you have until the end of the next business day. Even if the judge is just as much of a cock as the cop, think about this, the cop was on duty at 1230 am and pulled you over so chances are he doesn't even get off until 2 or 3 hours later. so if you fight it the cop will have to go to court during the day, when he would normally be sleeping, if your really lucky he will have to work the next shift as well.
