This is more complicated then I realized from the brief TV news accounts I saw yesterday (re the partial acquital/hung jury).
I’d say the cops screwed up. They should have kept Pangle overnight, and/or they should have towed his car. Had they done both things or either, by the time he got out / reclaimed his car, he’d have been sober, and if he started drinking and driving, it would have been a new bender and a new DUI offense.
Because they let him out prematurely, and because they let him reunite with his car prematurely, his subsequent actions can be seen as a continuation of the same drunken spree. Having arrested him for DUI, I would say that the police had an obligation to keep him in custody until he sobered up, and/or to keep him from reclaiming his car until he sobered up.
A distinct possibility: he was sober by the time they released him. The problem was (a) the police let him reunite with his car immediately upon release, and (b) it was still the same night. Had it been “the morning after” he might have gone home to bed, but as it was still “the night before,” he resumed drinking. And as his car was available, he also resumed driving. (Sounds as though the guy was an alcoholic or on the road to being one.)
This is exactly what the police proceedures used in other jurisdictions (tow car; keep drunk in jail overnight) are designed to prevent. It’s the police who are at fault. It seems quite likely that charging Powell (the friend) was a tactic to divert attention from the police role.
The “overkill” level of the charges vs. Powell were, I would say, business as usual on the part of the US criminal justice system: normal behavior seems to be, always charge everyone with the most serious possible charges.
Zev, another possible action at the wedding would have been to get others involved, assuming that other wedded guests were still present, as in, “Yo, folks, I don’t think X is fit to drive because “blank” – what does everyone else think?” For “blank” supply your reasons, either the amt you’d seen him consume, or the behavior he was exhibiting.
