General deterrent effects of police patrol in crime “hot spots”: A randomized, controlled trial

Sherman, Lawrence W., Weisburd, David·1995·Justice Quarterly

Abstract

Many criminologists doubt that the dosage of uniformed police patrol causes any measurable difference in crime. This article reports a one-year randomized trial in Minneapolis of increases in patrol dosage at 55 of 110 crime “hot spots,” monitored by 7,542 hours of systematic observations. The experimental group received, on average, twice as much observed patrol presence, although the ratio displayed wide seasonal fluctuation. Reductions in total crime calls ranged from 6 percent to 13 percent. Observed disorder was only half as prevalent in experimental as in control hot spots. We conclude that substantial increases in police patrol presence can indeed cause modest reductions in crime and more impressive reductions in disorder within high crime locations.

  • Many crime problems can be reduced more efficiently if police officers focused their attention on persistent high-activity crime places.

    “A number of researchers have argued that many crime problems can be reduced more efficiently if police officers focused their attention to these persistent high‐activity crime places (Braga & Weisburd, 2010; Sherman & Weisburd, 1995; Weisburd, 1997).”

  • Substantial evidence shows proactive policing can have meaningful effects on crime, especially when it is focused at crime hot spots.

    “There is now substantial evidence that proactive policing can have meaningful effects on crime, especially when it is focused at crime hot spots—small areas, such as street segments that produce a substantial part of the crime problem (4–6).”
  • The Minneapolis Hot Spots study found modest but statistically significant reductions in total crime calls for service ranging from 6% to 13%.

    “Modest, but statistically significant reductions in total crime calls for service ranging from 6% to 13%”

  • The patrol treatment in the Minneapolis Hot Spots experiment was disrupted during summer months due to a peak in the overall calls for service received by the Minneapolis Police Department and a shortage of officers due to vacations; this situation was further complicated by changes in the computerized calls for service system implemented in the fall.

    “The patrol treatment in the Minneapolis Hot Spots experiment (Sherman & Weisburd, 1995, pp. 638–639) was disrupted during summer months due to a peak in the overall calls for service received by the Minneapolis Police Department and a shortage of officers due to vacations; this situation was further complicated by changes in the computerized calls for service system implemented in the fall.”

  • Many crime problems can be reduced more efficiently if police officers focused their attention on these deviant places.

    “A number of researchers have argued that many crime problems can be reduced more efficiently if police officers focused their attention to these deviant places (Sherman and Weisburd 1995; Weisburd and Green 1995a).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
