When a statute or ordinance provides that criminal negligence suffices to establish an element of an offense, such element also is established if a person acts intentionally, knowingly or recklessly. When recklessness suffices to establish an element, such element also is established if a person acts intentionally or knowingly. When acting knowingly suffices to establish an element, such element also is established if a person acts intentionally. (Ord. 1145-85 § 15(2), 1985.)
