“My getting arrested for DUI was actually part of my sobriety plan”.
Now I really have heard it all.
One night (or 30 days or whatever) doesn’t prove anything. If he really has had a permanent change of heart, that will become apparent over time. It sounds to me like an alcoholic trying to assert that his drinking is not out of control, No matter how absurd this sounds to anyone else.
(How on earth does one deliberately get a DUI? Did he wake up in the morning, shotgun six beers, and then hop into his car and drive circles around the police station waiting for them to notice him? Even if this is fact what he did ... the reason DUI is illegal is because it is dangerous. During the time he was out there driving drunk, even if it was “planned”, he could have killed someone. This does not speak well of his mental processes).
