If it's his first time he might not even get jail time, just an ignition interlock which for somebody as wealthy as him doesn't matter at all he can just have someone drive him around anyways. I'm actually completely shocked that he was driving at all, I figured none of these people bothered driving once they could afford not to.

I'm willing to bet that they will charge him with something, but nothing that actually could be considered a punishment. The fact that they have already reversed and decided to do this to me means that they figure it is not worth it to expend ammo just to protect this guy from something as simple as a DUI given all the attention.
