Except as provided in paragraph (2) of this subsection, a State official or employee may not directly or indirectly monitor or record in any manner a telephone conversation made to or from a State unit. If prior approval is granted by the Attorney General, a State official or employee may monitor or record a telephone conversation: on telephone lines used exclusively for incoming police, fire, and rescue calls; or with recorder-connector equipment that automatically produces a distinctive recorder tone repeated at approximately 15-second intervals. A person who violates this section is guilty of a misdemeanor and on conviction is subject to a fine not exceeding $1,000. Conviction of a violation of this section is also grounds for immediate dismissal from State employment.
