At the same time, Mike Gennaco, who heads the Office of Independent Review, said an initial review of the case found that no laws had been broken and that the arrest had been handled within departmental policy.
Still at issue is whether Gibson -- who issued a second apology Tuesday explicitly acknowledging that he had made anti-Semitic remarks and asking to meet with Jewish leaders -- was given special treatment by sheriff's officials because of his celebrity status.
Sheriff's Department officials confirmed to The Times on Tuesday that a uniformed deputy drove Gibson from the Malibu-Lost Hills station to a tow yard to retrieve his Lexus LS sedan after he was released on bail Friday morning. Department spokesman Steve Whitmore said the 10-mile ride in a marked patrol car was not unusual.
"We do this for someone from time to time at all of our stations," he said, adding that officials decided to drive Gibson to avoid a confrontation with gathering media.
But one department source, who asked not to be identified because of the case's sensitivity, said it was a courtesy rarely extended to other suspects at the station.
Gennaco expressed surprise that Gibson had been driven by a deputy and said he would look into it. He said the decision to drive the actor could well be within policy, depending on why it was made.
Earlier in the day at a news conference outside his office in Commerce, Gennaco criticized the department's initial handling of the case. Reporters were not initially informed of Gibson's profane outbursts, attempt to escape custody and repeated threats to the arresting deputy. Instead, Whitmore initially described the arrest as "without incident."
"If I described what I know about the arrest, I'm not sure I would have used those words," Gennaco said.
In his comments Tuesday, broadcast live by cable and local media, Gennaco confirmed that the part of the arrest report detailing Gibson's "increasingly belligerent" behavior had been removed from the original report and purposely placed in a supplemental document by station-level supervisors. However, Gennaco said he had found no evidence so far that the decision had been directed, or even discussed, by Sheriff Lee Baca or other top officials.
Gennaco said it was not necessarily unusual to break an arrest report into more than one part, adding that it is sometimes done to protect the integrity of an investigation.
"Was the modification of this report done in a way so that the disclosure of information to the public would somehow be altered?" Gennaco asked. "I don't have the answer to that question."
Gennaco said that his probe was in its early stages and that he still had "some concerns about the access to that information."
Gibson was pulled over about 2:30 a.m. Friday by Deputy James Mee, who said the actor was driving more than 80 mph in a 45-mph zone on Pacific Coast Highway. Mee said he smelled alcohol on Gibson's breath and asked him to submit to Breathalyzer and field sobriety tests. According to sheriff's officials, Gibson's blood alcohol level measured .12% at the scene; the legal limit is .08%. An open bottle of tequila, one-quarter empty, was found in the vehicle.
In a part of the arrest report leaked last week to the celebrity website www.tmz.com, Mee wrote that after Gibson realized he was going to be arrested, he grew uncooperative and abusive. Gibson "blurted out a barrage of anti-Semitic remarks" and told Mee: "The Jews are responsible for all the wars in the world." Then he asked Mee, who is Jewish: "Are you a Jew?"
The Academy Award-winning director, who had denied charges of anti-Semitism made by some Jewish groups when he released his controversial 2004 blockbuster "The Passion of the Christ," issued a second apology Tuesday explicitly dealing with his anti-Jewish statements during the arrest.
"I want to apologize specifically to everyone in the Jewish community for the vitriolic and harmful words that I said to a law enforcement officer the night I was arrested on a DUI charge," the statement said.
Gibson had previously apologized for "despicable" behavior, but several prominent Jewish leaders said that wasn't enough.
The new statement satisfied some critics.
