  situations.
    2. Notwithstanding the provisions of any general, special or local law
  or  of  any county, city or village charter, the chief executive officer
  of a local government,  whenever  he  deems  that  the  public  interest
  requires  it, may request the chief executive officer of any other local
  government to detail, assign and make available for duty and use in  the
  local  government  for which the request is made any part of the forces,
  equipment and supplies of the police department, police force or parkway
  police force of the local government of which the request is  made.  The
  chief  executive officer of the local government of which the request is
  made is hereby authorized and empowered to grant the request so made.
    3. A local government may, by local law,  delegate  to  the  chief  of
  police  of  its  police  department  or  police  force the powers hereby
  granted to a  chief  executive  officer  to  request  and  grant  police
  assistance.
    4.  If  the  chief  executive  officer of any such local government is
  absent or disabled, the chief of police of the local government may make
  any such request or may grant any such request, as the case may be.
    5. The local government receiving police aid pursuant to this  section
  shall  assume  the  liability  for  all  damages  arising out of any act
  performed in rendering such aid and shall reimburse the assisting  local
  government  for any moneys paid by it for salaries or for other expenses
  incurred by it including damage to or loss of equipment and supplies. An
  assisting local government may assume such  loss,  damage,  expenses  or
  cost  for  such  equipment  and supplies and donate such services to the
  receiving local government. While engaged in duty and rendering services
  in such local  government  the  officers  and  members  of  such  police
  department  or  police force shall have the same powers, duties, rights,
  benefits, privileges and immunities as if  they  were  performing  their
  duties  in  the  local  government  in  and  by  which they are normally
  employed.
