What act labeled Hearst a fugitive rather than a kidnap victim?

Patricia was involved in a shootout on the streets of Los Angeles that led police back to the other members of the SLA. The fact that she fired a gun on a busy street to save members of the SLA swung public opinion against her. She became a true fugitive instead of a kidnap victim. Police had a lengthy firefight with the other six SLA members and they all died.
