It is unclear that killings committ

It is unclear that killings committed as
an act of war would likely have been included under
the heading of serial murder by any researcher.
Similarly, it is not clear why political assassins would
be excluded, while organized crime assassins would
remain under the heading of serial murder. Further,
although it was not likely the authors’ intentions, this
definition may imply to some that any act of multiple
killings occurring on a military base would not be
included under the heading of serial murder. Yet a
soldier who systematically killed several of his or her
own comrades, or prisoners of war could reasonably
be labeled a serial murderer.
Each of these studies presented a valiant attempt
to operationally define serial murder, and the deficiencies
of each approach detailed the difficulties of
attaining a definition which was both reasonably
inclusive of all serial murderers, yet capable of
discriminating between serial murderers and other
groups of homicide perpetrators.
