How to assess the effects of the policy of Nicolas Sarkozy, Home Secretary in France from May 2002 to March 2004? An analysis of the statistics and, in particular, of the way they were construed reveals that the results were ambiguous, because law enforcement was centered on the state’s duty to enforce the law while police services were being asked to show a decrease in delinquency so as to prove that the new policy was effective. On the other hand, an analysis of polls about how public opinion felt about law and order indicates that the minister’s tough talk was effective to a degree, especially when feelings of insecurity were strongly politicized prior to presidential elections in April 2002. This analysis sheds light on the distance between the practical and purely political effectiveness of a policy of law and order.
