More info at www.shouselaw.com/self-defense.html California's rules of self-defense allow you to use force in defending and protecting third parties, as this criminal defense lawyer explains. Included in California's right of self-defense is the right to intervene in the 'defense of others.' However, to count as a lawful and excusable use of force, the other person must be facing an immediate threat of harm and the amount of force or violence used in the defense of the third party must be proportionate to the level of threat that he or she faced.
