(1) The ignorance or mistake negatives the state of mind for the commission of the offense; or
(2) The statute defining the offense or a statute related thereto expressly provides that the ignorance or mistake constitutes a defense or exemption; or
(3) The ignorance or mistake is of a kind that supports a defense of justification as defined in this Criminal Code.
