   family of the victim.
   
   D. This section shall not be construed to authorize the introduction
   of any evidence secured in violation of the Constitutions of the
   United States or of the State of Oklahoma. The state and the defendant
   or his counsel shall be permitted to present argument for or against
   sentence of death.
