(d) Nothing in this part or §§ 39-13-601 — 39-13-603 shall be construed as permitting the interception of a wire, oral or electronic communication that is made privileged by law unless the judge issuing the order for the interception finds probable cause to believe that all parties to the privileged communication are criminally responsible for the commission of a homicide offense, conspiracy to commit a homicide offense or commission of a violation of § 39-17-417(j).

(e) When an investigative or law enforcement officer, while engaged in intercepting wire, oral or electronic communications in the manner authorized in this part, intercepts wire, oral or electronic communications relating to offenses other than those specified in the order of authorization, the contents thereof and evidence derived therefrom, may be disclosed or used as provided in subsections (a) and (b).
