TV news outlets and other news media were unsuccessful Thursday in persuading the Los Angeles County Sheriff's Department to release video and audio tapes of Mel Gibson taken by officers following his DUI arrest on July 28. "They are part of the evidence," Sheriff's Department spokesman Steve Whitmore told the Associated Press. "Once everything is done and the case is wrapped up we certainly can revisit it.", the website that first reported the details of Gibson's arrest, immediately filed a demand under the California Public Records Act for the tapes to be released, saying that they would disclose whether the department extended preferential treatment to the actor. "We want the tapes not just because of Mel Gibson but because the tape puts the conduct of the sheriff's department in context," said Harvey Levin, the attorney who heads TMZ.
