France's policy in matters of public security is based on the followin
g elements: the government (public and military police force, public p
rosecutor's office, prefecture) firmly placed at the centre, a subordi
nation to the imperatives of law and order, the primacy of repression,
an extreme variability in the priorities for petty and middle crime,
etc. The article explains how and why this type of policy came to exis
t. It is mainly the result of a day-to-day, on-the-job development of
the interdependence of rights between the various actors when dealing
with public security issues; in some cases leading to certain modes of
cooperation, but not in all. The method adopted to analyse the observ
ations collected during a survey in three departments in France was th
at of systemic analysis of collective action (confronted with what is
known as institutional analysis). First, it makes clear the narrow mar
gin which the heads of public service currently have in order to impos
e national, homogeneous priorities. Secondly, it shows the lack of dev
elopment of the supposed partnerships and their tendency towards preve
ntion or non-judicial handling of problems.
