A lady lawyer did that in a town near me.
She hit a farm tractor, left the scene, drove home, and was never charged with DUI even though she was smashed when officers got to her house just moments after she pulled in her garage.
A guy I used to hunt with got arrested for DUI and was taken to jail. He calls daddy, the State Judge. He claims there is no record that it ever happened. All of the documentation just evaporated into thin air.
This all occurred after they cracked down on DUI’s.
