OWI penalties vary depending upon where you live... but they all carry consequences — even if you have an attorney. Why does he need one? If he was driving drunk and got arrested - it is what it is. More time in jail - perhaps to dry out and seek treatment. Maybe a good thing.
The real burden on your family will be the huge auto insurance rates - for a long, long time.
Those are the consequences. Unfortunately, it effects every other person the offender is financially associated with... you and your family. These are the burdens we take on when we opt to stay in an alcoholic relationship.
