After spending a few hours in jail, he was released. Later he told his colleagues and the media about the situation. He said that it was a terrible error in judgement and apologized.
One of the many reasons we need a well funded and well designed transit system is take people home when they're not suitable to drive. For the driver, being arrested for DUI can be traumatic. The fines, the cost of fighting the charge, and the subsequent increase in insurance premium are high. DUI can also hurt your career if driving is a part of the job. For the community, drunk drivers pose a hazard for all road users.
The police are cracking down hard on drunk drivers especially at nights and around certain holidays. It is more likely to get pulled over for the little things (like broken lights, or just speeding a little bit) than at other times so that the cops can check whether you're sober.
If you drank, you should avoid driving. If you don't have a sober friend to drive you home, a train ride, a bus ride, or a cab ride is worth it. Even if you have to pay $20-30 for a cab, it is still cheaper than a ride on a police car to jail after being caught.
