In an interview with The Times on Monday, Mee called the incident "just another routine stop that just got a little escalated.... This is just another drunk driving incident. It just happened to be a celebrity versus Joe Blow public."
Lee Baca, whose department has been criticized for giving the actor special treatment, has insisted that Gibson should only face charges related to the DUI and that his behavior after the arrest should not be an issue in his prosecution.
"Our job is not to [focus] on what he said. It's to establish his blood-alcohol level when he was driving," Baca told The Times on Saturday.
Jane Robison, a spokeswoman for the Los Angeles County district attorney's office, declined to elaborate on the specific reasons prosecutors did not seek charges beyond those directly related to drunk driving.
"Prosecutors reviewed all of the reports, all the audiotape from the scene, all the videotape taken at the station, all the evidence," she said. "And we filed the charges we believe we can prove beyond a reasonable doubt."
Attorney Lawrence Taylor, who has defended DUI clients for 35 years, said he has seen similar cases thousands of times.
"Except for the comments he made and who he is, this is a very common, run-of-the-mill businessman case," Taylor said.
Gibson's attorney, Blair Berk, declined to comment on the charges being filed.
"I will be the one lawyer not discussing the ongoing case," she said.
Gibson has issued two public apologies since his arrest and said he suffered a relapse in his longtime battle with alcoholism.
