Using or disclosing information obtained through illegal wiretapping is prohibited if there is reason to know the information was obtained illegally. Anyone who is not "visibly present" during a conversation who overhears or records the conversation without the consent of at least one of the parties commits a felony carrying the same punishment as a telephone interception, as does anyone who discloses the contents of such a conversation. Colo. Rev. Stat § 18-9-304.
However, nothing in these statutes "shall be interpreted to prevent a news agency, or an employee thereof, from using the accepted tools and equipment of that news medium in the course of reporting or investigating a public and newsworthy event." Colo. Rev. Stat. § 18-9-305.
