The State of California has the biggest population in all of the United States of America. With the vast population, it is quite a challenge for police officers and other arresting authorities to keep the streets of California safe for its citizens. With an intention to increase security within the state, the government made arrest documents open for public access. Arrest documents are found at a county, state, and federal level. The Public Records Ombudsman is a good place to start searching for the documents. You can head to their office and file a request there. But if you are aware of which county the documents were initially filed, you can access the documents from there. In the case of Sonoma Arrest Records, they are available at the Superior Court of California County of Sonoma.
