Gibson has also been accused of anti-Semitism with his portrayal of the Jews in his film The Passion Of The Christ. And he refused to criticise his father, who has claimed the Holocaust was mostly "fiction".
The star was stopped by police early on Friday for speeding near his Malibu home. A part-empty bottle of tequila was found in his car.
A bizarre melée then ensued, with Gibson apparently trying to escape, his alleged propositioning of the arresting officer-with explicit suggestions and claims that, while handcuffed, he claimed he owned Malibu and would spend all his money to "get even".

Gibson, a Catholic traditionalist, blamed his actions on alcoholism. "I did a number of things that were very wrong and for which I am ashamed," he said. "I have battled with the disease of alcoholism for all of my adult life and profoundly regret my horrific relapse."
