Sec.  35.15  Justification; use of physical force in defense of a
                   person.
    1.   A  person  may, subject to the provisions of subdivision
two, use physical force upon  another  person  when  and  to  the
extent  he or she reasonably  believes  such  to be necessary to defend
himself, herself or a third person from what he or she reasonably believes to  be
the  use or imminent use of unlawful physical force by such other
person, unless:
    (a)   The  latter's conduct was provoked by the actor 
with intent to cause physical injury to another person; or
    (b)  The actor was the initial aggressor; except that in such
case the use of physical force is nevertheless justifiable if  the actor 
has  withdrawn  from  the  encounter and effectively communicated
such withdrawal to such other person but the latter  persists  in
continuing  the incident by the use or threatened imminent use of
unlawful physical force; or
    (c)   The  physical force involved is the product of a combat
by agreement not specifically authorized by law.
    2.   A  person may not use deadly physical force upon another
person under circumstances specified in subdivision one unless:
    (a)  The actor reasonably believes that such other person is using
or about to use  deadly  physical  force.   Even  in  such  case,
however,  the actor may not use deadly physical force if he or she knows
that with complete safety to oneself and  others  he or she may avoid
the  necessity of so doing by retreating; except that the actor is under
no duty to retreat if he or she is:
    (i)  in his or her dwelling and not the initial aggressor; or
    (ii)  a police officer or peace officer or a person assisting
a police officer or a peace officer at  the  latter's  direction,
acting pursuant to section 35.30; or

  (b) He or she reasonably believes that such other  person  is  committing  or
attempting  to  commit  a  kidnapping,  forcible rape, forcible 
criminal sexual act or robbery; or
(As amended L. 2003, c. 264, effective 11/1/03). 

    (c)   He or she reasonably  believes  that  such  other  person  is
committing  or  attempting  to  commit  a   burglary,   and   the
circumstances  are  such that the use of deadly physical force is
authorized by subdivision three of section 35.20.
