The term "chief executive officer" shall mean:  (1) In the case of a county, the  county  executive  unless  there  is none, in which case it shall mean the county manager if there is one, or the  chairman  of  the board of supervisors if there is neither a county executive nor county manager.  (2) In the case of cities, the mayor, except in those cities having  a city manager, it shall mean such city manager.  (3) In the case of towns, the supervisor or presiding supervisor.  (4)  In  the  case  of  villages,  the mayor, except in those villages having a president or manager, it shall mean such latter officer.   c. The term "chief of police" shall  include  any  police  officer  in command  of  the police department or police force of a local government during the absence, illness or disability of the chief of police or  who is authorized to exercise the powers of the chief of police in emergency 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.
