Detailed Answer

Under Washington law, police reports are public records governed by the Public Records Act (RCW 42.56). Although state law does not prescribe a formal procedure entitled “amendment,” most law enforcement agencies allow you to submit new information or request a supplemental report when you believe the original record contains errors or omissions. To build a persuasive request, gather documentation that directly addresses the disputed facts.

Key Types of Supporting Evidence

• Witness affidavits: Sworn statements from individuals who observed the incident, describing what they saw and when they saw it.
• Photographs and videos: Surveillance footage, dash-cam recordings or still images that depict the scene, people involved or property damage.
• Medical and repair records: Hospital records, doctor’s reports, bills or repair invoices that confirm injuries or damage and link them to the incident.
• Location data: GPS logs, cell-phone records or telematics data establishing your precise location and timeline.
• Correspondence with officers: Emails, letters or notes showing prior communications pointing out discrepancies in the report.

When you submit your request:

1. Identify the report by case number, date, location and officer name.
2. Specify the exact portion you believe is incorrect or incomplete.
3. Attach your supporting evidence, clearly label each document, and explain how it demonstrates an error or omission.
4. Send the request to the agency’s public records custodian—ideally by certified mail or secure email—and retain proof of delivery.

The agency will review your submission. If they agree the new material sheds light on inaccuracy, they may add a supplemental report or annotate the original record. If the agency denies your request, you may pursue judicial remedies.

Relevant Washington Statutes

• Public Records Act (RCW 42.56): Governs inspection and copying of police reports. See definitions at RCW 42.56.070 and civil action remedies at RCW 42.56.550.

Helpful Hints

• Be concise and precise: Pinpoint the exact wording or data you believe is wrong.
• Organize evidence chronologically: A clear timeline highlights inconsistencies.
• Keep detailed copies: Maintain records of every document you submit or receive.
• Follow up promptly: If you don’t hear back within the agency’s stated PRA response time (5 business days), send a reminder.
• Consider professional guidance: If your request is denied or you face complexities, consult an attorney familiar with Washington public records and administrative law.
