Or a drugged up Britney... It isn't just so many cars/people, if this had happend years ago, it wouldn't have been news because nobody arrested big name stars and if they did, the media was not involved. The police want to be seen as treating stars as the same as anyone else...better that they pulled him over than him being hurt or hurting someone else in an accident.
They said on the news that Fox had offered to drive home anyone who "shouldn't be driving" and Sutherland refused the service.
