Nikon, actually his crime was riding against traffic. It's not a major crime, but it is illegal. He got caught. When he was caught, he didn't have ID. This is a minor logistical issue, and not a crime. He appears to have made it a big issue by screaming and swearing at the cop. Now, the cops could have just given him the ticket and walked away. That would have been big of them. But when someone is screaming and yelling at you, it doesn't make you want to accommodate them--so they took him to the station to ID him. They solved the minor logistical issue in the way that would cause Baldwin the most hassle possible, because he was a jerk to them. Yeah, it was a petty thing to do, but then again, it appears Baldwin started the fire.
