California Code, Penal Code - PEN § 6128

(a) The Office of the Inspector General may receive communications from any individual, including those employed by any department, board, or authority who believes he or she may have information that may describe an improper governmental activity, as that term is defined in subdivision (c) of Section 8547.2 of the Government Code.  It is not the purpose of these communications to redress any single disciplinary action or grievance that may routinely occur.

(b) In order to properly respond to any allegation of improper governmental activity, the Inspector General shall establish a toll-free public telephone number for the purpose of identifying any alleged wrongdoing by an employee of the Department of Corrections and Rehabilitation.  This telephone number shall be posted by the department in clear view of all employees and the public.  When requested pursuant to Section 6126, the Inspector General shall initiate a review of any alleged improper governmental activity.

(c) All identifying information, and any personal papers or correspondence from any person who initiated the review shall not be disclosed, except in those cases where the Inspector General determines that disclosure of the information is necessary in the interests of justice.
