TMZ has learned that Mel Gibson went on a rampage when he was arrested Friday on suspicion of drunk driving, hurling religious epithets. TMZ has also learned that the Los Angeles County Sheriff’s department had the initial report doctored to keep the real story under wraps.
TMZ has four pages of the original report prepared by the arresting officer in the case, L.A. County Sheriff’s Deputy James Mee. According to the report, Gibson became agitated after he was stopped on Pacific Coast Highway and told he was to be detained for drunk driving Friday morning in Malibu. The actor began swearing uncontrollably. Gibson repeatedly said, “My life is f****d.” Law enforcement sources say the deputy, worried that Gibson might become violent, told the actor that he was supposed to cuff him but would not, as long as Gibson cooperated. As the two stood next to the hood of the patrol car, the deputy asked Gibson to get inside. Deputy Mee then walked over to the passenger door and opened it. The report says Gibson then said, “I’m not going to get in your car,” and bolted to his car. The deputy quickly subdued Gibson, cuffed him and put him inside the patrol car.
[…] The report says Gibson then launched into a barrage of anti-Semitic statements: “F*****g Jews… The Jews are responsible for all the wars in the world.” Gibson then asked the deputy, “Are you a Jew?”
[…] Deputy Mee then wrote an eight-page report detailing Gibson’s rampage and comments. Sources say the sergeant on duty felt it was too “inflammatory.” A lieutenant and captain then got involved and calls were made to Sheriff’s headquarters. Sources say Mee was told Gibson’s comments would incite a lot of “Jewish hatred,” that the situation in Israel was “way too inflammatory.” It was mentioned several times that Gibson, who wrote, directed, and produced 2004’s “The Passion of the Christ,” had incited “anti-Jewish sentiment” and “For a drunk driving arrest, is this really worth all that?”

NY Times:

“If it’s true what’s reported, frequently hatred, bigotry and prejudice, which is controlled, explodes at moments of stress and crisis,” said Rabbi Abraham H. Foxman, national director of the Anti-Defamation League. “Liquor loosens the tongue of what’s in the mind and in the heart, and in his mind and in his heart is his conspiracy theory about Jews and hatred of Jews.”

Gibson, whose father is a known Holocaust denier, is currently at work on a mini-series about the Shoah for ABC television.
