Dumb and dangerous and I in no way condone, but something to consider ...
Before the Mad Mothers succeeded in getting the threshold lowered, the magic line for DUI was .10, not .08. He tested nine one-thousanths of a millimeter over the old threshold. In my days as a prosecutor I would have automatically lowered his charge to Careless Driving, as the machine measuring BAC has a margin of error that his test would have fallen into. In other words, I could not have elicited sworn testimony that he was actually OVER the .10 requirement. He was right on the line, so likely not falling down shitfaced.
On the other hand ... Remember when the Brass Rail installed a BAC machine? The theory was that you could blow a sample to see if you were OK to drive. The reality was you'd spend the night pounding drinks to see how high you could test. It took a couple of hours to get above that .10 threshold, so he definitely had more than a few. Not good right before a game, but hardly shocking for a college kid.
Make him run stadium steps until he pukes and call it good. He'll get probation in county court
