Opinion
— Pеtitioner Glenn Engstrom seeks mandate to compel respondent, the Alameda County Superior Court, to grant discovery. Petitioner is charged with murder of Faustin Feehan and felonious assault on Reginald Rassette and Brent Bauer. In an affidavit in support of a discovery motion, petitioner’s attorney represented that at the preliminary hearing and in pretrial statements to the police, prosecution witnesses stated that petitioner had come to the home of Anna Coehlo, and that while there he got into an argument with the deceased. During an ensuing scuffle a gun was seen in petitioner’s hand; petitioner assertedly shоt the deceased and then fired several more shots, injuring Rassette and Bauer. Several persons in the room then disarmed petitioner, who jumped out the window and escaped. According to the affidavit, рetitioner will raise the defense of self-defense. His version of the incident, as told to the police, was that he had been living with Anna Coehlo; after the relationship broke up, Miss Coehlo was hostile and bitter tоward petitioner. She called him and asked him to remove his personal belongings from her home; when he arrived he was attacked by the deceased and several other persons. “Someone” prоduced a gun and began hitting petitioner with it. Petitioner grabbed the weapon and it discharged three times.
*243 By means of the discovery motion, petitioner sought the following information:
1. The felony conviction, detention and arrest records of the victims “which relate to any act or attempted act of violent or assaultive conduct” to prove that the victims initiated the attack.
2. The felony conviction records of prosecution witnesses (named in the motion) to impeach their credibility.
3. Portions of the detention, arrest and/or conviction records of the witnesses which relate to acts or attempted aсts of violence “to prove that said witnesses conspired to and did initiate the chain of events which led to the alleged offenses when they attacked defendant, . . .”
4. “Any police reports, memorandа, or other information in the actual or constructive possession of or available to the District Attorney of the County of Alameda” which relate to acts or attempted acts of violence by аny of the victims or witnesses to prove that the victims and witnesses conspired to and did initiate the attack. The motion was denied by the trial court.
The issue before us is not whether the district attorney should be required to disсlose relevant materials in his possession; that obligation is conceded (see

(1967)

We have concluded that thе court should require the prosecution

to make diligent good faith efforts to obtain and make available to the defense pertinent information in the possession of other agencies which are parts of the criminal justice system. It has already been held that a trial court may, in its discretion, order a prosecuting witness in a rape case to submit to a psychiatric examination
(Ballard
v.
Superior Court
(1966)
The Attorney General argues that conviction records are kept by the Bureau of Criminal Identification and Investigation of the Department of Justice, and the district attorney has no duty to obtain these reсords for the defendant. Penal Code section 11105 1 does not authorize the bureau to provide records directly to private individuals; but there is no prohibition against giving an accused person access to information pertinent to his defense.
Unless criminal conviction records of prosecution witnesses are made available to the defense, the defendant would be at a great disadvantage. The рrosecution has access to such records to impeach defense witnesses, but the defendant would not have equal access to criminal records. The effort required by the prosecution to obtain conviction records from the *245 Bureau of Criminal Identification and Investigation is minimal compared with the potential value of such records to the defense. Therefore we conclude that the рrosecution should be required, on request, to obtain and make available information concerning felony convictions of prosecution witnesses. 2 If such information is obtained by the prosecution from thе Bureau of Criminal Investigation and Identification of the Department of Justice, the entire “rap sheet” need not be disclosed.
Arrest records and other police records of criminal activity, also sоught by petitioner, could not be used for impeachment purposes; and their discovery could not be justified on impeachment grounds. (See Evid. Code, § 787.) But specific acts of aggression by the alleged victim may bе admissible to show that the victim was the aggressor; such evidence would be material when the defense is self-defense, or where the defendant seeks to show mitigating circumstances to reduce the charge.
(In re Ferguson, supra,
Finally, petitioner seeks to discover portions of the detention, arrest, or conviction records of (nonvictim) witnesses and all other “police reports, memoranda, or other information in the actual or сonstructive possession of or available to the District Attorney” which relate to any act or attempted act of violence or “assaultive conduct” by a victim or other witness. The court actеd properly in denying these requests; they lacked sufficient specificity.
