The decision-making of crisis has the character of haste have
great influence to outcome but always deceide by police
officer himself. Facing this situation, it seems that "Cusp
Decision- Making Catastrophe Model" can offer an explanation
for active or passive behavior of decision maker. This paper
present "benefits conflict" and "evidence sufficiency" as the
two control variable of cusp catastrophe model that determine
the decision active or or passive. Through the cusp model,
we found that there were five basic types of police''s decision
in crisis: (1) active type; (2)passive type; (3) dilemma type;
(4) active change to passive; (5) passive change to active.
We special interested in the way of change, suddently or
smoothly, between the active and passive decision behavior.
We show some real case also to reflect each type of police''s
decision in crisis.
