How to File a Civilian Complaint with the San Bernardino County Sheriff's Department (for families in Big Bear)

People typically file complaints about excessive force, disrespectful behavior, harassment, discrimination, or situations where safety or medical needs were ignored. If you decide to move forward, write down what you remember while it's fresh: the date and time, location, who was involved (names or badge numbers if you have them), and contact info for any witnesses. Gather any photos, screenshots, medical paperwork, or other records tied to the incident - having everything in one place helps you describe the situation clearly.

The Sheriff's Department uses a

Need to mail your complaint or have questions about where to send paperwork? Use this address: San Bernardino County Sheriff's Department, 157 W. 5th Street, 3rd Floor, San Bernardino, CA 92415. You can also call (909) 387-5700.

Before your complaint can be accepted, you'll need to read and sign a Penal Code 148.6 advisory statement. This acknowledgment confirms you understand your right to complain - and that the process carries legal responsibilities. Expect this as part of the paperwork so it doesn't catch you off guard.

Your complaint doesn't vanish into a short-term inbox. The Sheriff's Department must keep civilian complaints - and any related reports or findings - for at least five years. That's one reason to take your time with dates, details, and supporting documents: what you submit becomes part of the record.

Caution: It is against the law to make a complaint you know to be false. Knowingly filing a false complaint can lead to misdemeanor prosecution.

Once the investigation wraps up, the Department labels the result one of five ways. Unfounded means the allegation was clearly not true. Exonerated means the incident happened, but the officer's actions didn't violate law or policy. Sustained means the investigation confirmed misconduct. Not Sustained means there wasn't enough evidence to prove or disprove the allegation. Frivolous means the complaint was totally without merit or made solely to harass the officer.

Regardless of the outcome, the Sheriff's Department says it will investigate complaints in a timely and professional manner. In practice, you may be contacted for follow-up details or clarification - so keep your notes and copies handy in case you need to revisit the timeline.
