§ 35.30   Justification;  use  of physical force in making an
                   arrest or in preventing an escape.
    1.   A  police  officer  or a peace officer, in the course of
effecting or attempting to effect an arrest, or of preventing  or
attempting  to  prevent the escape from custody, of a person whom
he or she reasonably believes to have  committed  an  offense,  may  use
physical force when and to the extent he or she reasonably believes such
to be necessary to effect the arrest, or to  prevent  the  escape
from custody, or in self-defense or to defend a third person from what he
or she reasonably believes to be the use or  imminent  use  of  physical
force;  except  that  deadly physical force may be used for such
purposes only when he or she reasonably believes that:
    (a)  The offense committed by such person was:
    (i)   a felony or an attempt to commit a felony involving the
use or attempted use or threatened imminent use of physical force
against a person; or
    (ii)  kidnapping, arson, escape in the first degree, burglary
in the first degree or any attempt to commit such a crime; or
    (b)   The offense committed or attempted by such person was a
felony and that, in the course of resisting  arrest  therefor  or
attempting  to  escape  from custody, such person is armed with a
firearm or deadly weapon; or
    (c)   Regardless  of  the  particular  offense  which  is the
subject of the arrest or attempted  escape,  the  use  of  deadly
physical force is necessary to defend the police officer or peace
officer or  another  person  from  what  the  officer  reasonably
believes  to be the use or imminent use of deadly physical force.
    2.   The  fact  that  a  police officer or a peace officer is
justified in using  deadly  physical  force  under  circumstances
prescribed  in paragraphs (a) and (b) of subdivision one does not
constitute justification for  reckless  conduct  by  such  police
officer  or peace officer amounting to an offense against or with
respect to innocent persons whom he or she is not seeking to  arrest  or
retain in custody.
     3.   A person who has been directed by a police officer or a
peace officer to assist such police officer or peace  officer  to
effect  an  arrest  or  to prevent an escape from custody may use
physical force, other than deadly physical force, when and to the
extent  that he or she reasonably believes such to be necessary to carry
out such police officer's or peace officer's direction, unless he or she 
knows  that  the  arrest  or prospective arrest is not or was not
authorized and may  use  deadly  physical  force  under  such
circumstances when:
    (a)   He or she reasonably  believes such to be necessary for
self-defense or to defend a third person from what he or she reasonably believes to  be
the use or imminent use of deadly physical force; or
    (b)   He or she is directed or authorized by such police officer or
peace officer to use deadly physical force unless he or she knows  that
the  police officer or peace officer is not authorized to
use deadly physical force under the circumstances.
    4.   A  private  person  acting  on  his or her own account may use
physical force, other than deadly physical  force,  upon  another
person when and to the extent that he or she reasonably believes such to
be necessary to effect an arrest or to prevent  the  escape  from
custody of a person whom he or she reasonably believes to have committed
an offense and who in fact has committed such offense; and may
use  deadly  physical  force  for such purpose when he or she reasonably
believes such to be necessary to:
    (a)  Defend himself, herself or a third person from what he or she reasonably
believes to be the use or imminent use of deadly physical  force;
or
  (b)  Effect  the  arrest  of  a  person  who  has  committed   murder,
manslaughter  in  the  first  degree, robbery, forcible rape or forcible
criminal sexual act and who is in immediate flight therefrom.
    5.   A  guard, police officer or peace officer who is charged
with the duty of guarding prisoners  in a detention facility,  as
that term is defined in section 205.00, or while in transit to or
from a detention facility, may use physical force when and to the
extent  that  he  or she reasonably  believes  such  to  be necessary to
prevent the escape of a prisoner  from a  detention  facility  or
from custody while in transit thereto or therefrom.
