In addition, no such person shall regain eligibility for peace officer employment based upon any later order of the court setting aside, vacating, withdrawing, expunging or otherwise dismissing or reversing the conviction, unless the court finds the person to be factually innocent of the crime for which they were convicted at the time of entry of the order.

(b)
1. (1) A plea of guilty to a felony pursuant to a deferred entry of judgment program as set forth in Sections 1000 to 1000.4, inclusive, of the Penal Code shall not alone disqualify a person from being a peace officer unless a judgment of guilty is entered pursuant to Section 1000.3 of the Penal Code.
2. (2) A person who pleads guilty or nolo contendere to, or who is found guilty by a trier of fact of, an alternate felony-misdemeanor drug possession offense and successfully completes a program of probation pursuant to Section 1210.1 of the Penal Code shall not be disqualified from being a peace officer solely on the basis of the plea or finding if the court deems the offense to be a misdemeanor or reduces the offense to a misdemeanor.
(c) Any person who has been convicted of a felony, other than a felony punishable by death, in this state or any other state, or who has been convicted of any offense in any other state which would have been a felony, other than a felony punishable by death, if committed in this state, and who demonstrates the ability to assist persons in programs of rehabilitation may hold office and be employed as a parole officer of the Department of Corrections and Rehabilitation or the Division of Juvenile Justice, or as a probation officer in a county probation department, if the person has been granted a full and unconditional pardon for the felony or offense of which they were convicted. Notwithstanding any other provision of law, the Department of Corrections and Rehabilitation or the Division of Juvenile Justice, or a county probation department, may refuse to employ that person regardless of their qualifications.
(d) This section does not limit or curtail the power or authority of any board of police commissioners, chief of police, sheriff, mayor, or other appointing authority to appoint, employ, or deputize any person as a peace officer in time of disaster caused by flood, fire, pestilence or similar public calamity, or to exercise any power conferred by law to summon assistance in making arrests or preventing the commission of any criminal offense.
(e) This section does not prohibit any person from holding office or being employed as a superintendent, supervisor, or employee having custodial responsibilities in an institution operated by a probation department, if at the time of the person’s hire a prior conviction of a felony was known to the person’s employer, and the class of office for which the person was hired was not declared by law to be a class prohibited to persons convicted of a felony, but as a result of a change in classification, as provided by law, the new classification would prohibit employment of a person convicted of a felony.
(f) The Department of Justice shall supply the commission with necessary disqualifying felony and misdemeanor conviction data for all persons known by the department to be current or former peace officers. The commission shall be permitted to use the information for decertification purposes. The data, once received by the commission, shall be made available for public inspection pursuant to the California Public Records Act (Division 10 (commencing with Section 7920.000) of Title 1), including documentation of the person’s appointment, promotion, and demotion dates, as well as certification or licensing status and the reason or disposition for the person leaving service.
