Every person concerned in the commission of a gross misdemeanor or misdemeanor in violation of any city ordinance, whether he directly commits the act constituting the offense or aids or abets in its commission, and whether present or absent; and every person who directly or indirectly counsels, encourages, hires, commands, induces or otherwise procures another to commit a gross misdemeanor or misdemeanor, is a principal and shall be proceeded against and punished as such. The fact that the person aided, abetted, counseled, encouraged, hired, commanded, induced or procured, could not or did not entertain a criminal intent, shall not be a defense to any person aiding, abetting, counseling, encouraging, hiring, commanding, inducing or procuring him. (Ord. 480 § 1, 1969)
