Under what other circumstances can a "factual innocence" finding be obtained?
Under some broader statutes such as California's, anyone arrested for a crime they did not commit can petition the police and/or the court for an order finding him or her factually innocent. The burden of proof is on the petitioner to show that no reasonable person would think they were guilty. This standard is meant to exclude those who obtained dismissals from mere difficulty in proving guilt, or where perhaps witnesses were threatened off, or even someone who obtained an acquittal at trial, but well may have been guilty.
