(b) Any investigative or law enforcement officer who, by any means authorized by this part or §§ 39-13-601 -- 39-13-603, has obtained knowledge of the contents of any wire, oral or electronic communication or evidence derived therefrom may use the contents to the extent the use is appropriate to the proper performance of the officer's official duties.

(c) Any person who has received, by any means authorized by this part or §§ 39-13-601 -- 39-13-603, any information concerning a wire, oral or electronic communication, or evidence derived therefrom, intercepted in accordance with this part or §§ 39-13-601 -- 39-13-603 may disclose the contents of that communication or derivative evidence while giving testimony under oath or affirmation in any proceeding held under the authority of the state of Tennessee, or a political subdivision of the state, or of the United States, or a political subdivision of the United States.

(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). The contents and any evidence derived therefrom may be used under subsection (c) when authorized by a judge of competent jurisdiction where the judge finds on subsequent application that the contents were otherwise intercepted in accordance with this part or §§ 39-13-601 -- 39-13-603. The application shall be made as soon as practicable after the interception.
