Mel Gibson cover up?

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.

TMZ has learned that Deputy Mee audiotaped the entire exchange between himself and Gibson, from the time of the traffic stop to the time Gibson was put in the patrol car, and that the tape fully corroborates the written report.
