Is a criminal defendant entitled to the disciplinary and other records of a law enforcement officer?

In Pitchess v. Superior Court, supra, 11 Cal.3d at p. 537, the court determined a criminal defendant is entitled to a law enforcement officer's disciplinary and other records if the defendant can show the records are necessary as character evidence to show the officer's tendency to commit unlawful or improper acts. "Even upon a showing of good cause, however, the right of an accused to obtain discovery is not absolute. `In criminal cases, the court retains wide discretion to protect against the disclosure of information which might unduly hamper the prosecution or violate some other legitimate governmental interest.'" (Id. at p. 538.)
