(4) A person who is not the initial aggressor and is not engaged in unlawful activity shall have no duty to retreat before using deadly force under subsection (1) (e) or (f) of this section if the person is in a place where the person has a right to be, and no finder of fact shall be permitted to consider the person's failure to retreat as evidence that the person's use of force was unnecessary, excessive or unreasonable. (5) (a) The presumptions contained in subsection (3) of this section shall apply in civil cases in which self-defense or defense of another is claimed as a defense.
(b) The court shall award reasonable attorney's fees, court costs, compensation for loss of income, and all expenses incurred by the defendant in defense of any civil action brought by a plaintiff if the court finds that the defendant acted in accordance with subsection (1) (e) or (f) of this section. A defendant who has previously been adjudicated "not guilty" of any crime by reason of subsection (1) (e) or (f) of this section shall be immune from any civil action for damages arising from same conduct.
