Résumé
"The main focus of this study is immediate spatial displacement or diffusion to areas near the targeted sites
of a police intervention. This research represents the first attempt we are aware of to examine
displacement as a primary outcome, and thus it was designed to optimize the identification of
displacement and diffusion outcomes. Do focused prevention efforts simply move crime around the
corner? Or, conversely, do hot spots policing efforts that bring unusually high dosages of police presence
to target areas diffuse crime prevention benefits to areas immediately surrounding the target areas? To
answer these questions, two study sites were selected in Jersey City, New Jersey. One area had a high
concentration of drug and violent crime; the other was the site of a strong concentration of prostitution
activity."--Page 2.
