4) Zero tolerance for possession of child pornography. The legislation amends the child pornography possession statutes to permit the prosecution of an individual for possessing one matter (18 U.S.C. € 2252(a)(4)) or image (18 U.S.C. € 2252A(a)(5)) of child pornography. The existing statutes provided for prosecution of individuals possessing three or more matters or images. Both statutes are also amended to include an affirmative defense, for the possession of one matter or image, that the individual took reasonable steps to delete or destroy the matter or image or reported the existence of the visual depiction or child pornography to law enforcement authorities.
