The California Department of Justice is the department in the California executive branch under the leadership of the California Attorney General.
It has 4713 employees and a budget of $754 million. Among its major divisions and bureaus are:
Bureau of Firearms, which "is responsible for identifying individuals who are ineligible to acquire or possess firearms" and other weapons
Bureau of Gambling Control, which "regulates legal gambling activities"
Division of California Justice Information Services, which "facilitates the exchange of criminal justice intelligence among law enforcement agencies"
Division of Civil Law, which "both prosecutes and defends civil actions"
Division of Criminal Law, which "represent[s] the People of the State of California in criminal cases"

Besides its support of the California Attorney General's work, the Department is frequently mentioned in the newsmedia for (among other activities):
Its laboratory work. For example, in the 1995 trial of O. J. Simpson, the lead forensic chemist from the Department testified that DNA tests on blood samples from inside Simpson's Bronco "were 'consistent with' tests on blood taken from Mr. Simpson, his former wife, Nicole Brown Simpson, and her friend Ronald L. Goldman".
Its statistics, for example on weapons sales in California.
Its assistance to local law enforcement agencies, for example a database that "cross-reference[s] criminal history and firearms possession information".
