Comparison of Drug Control Strategies in San Diego, 1989 (ICPSR 9990)

Released/updated on: 2000-03-21
Geographic coverage: San Diego, United States, California
This study assesses the consequences for offenders of various drug enforcement strategies employed by the San Diego Police Department and profiles the factors that characterize street-level and mid-level dealers, drug users, and the drug market. The drug enforcement strategies examined include the use of search warrants, body wires, police decoys, surveillance, officer buys and sells, wiretaps, and sweeps. Measures of the consequences of arrests include drug and property seizures, convictions, and sentences. The data were drawn from police and court records of drug arrests made by three special sections of the police department in San Diego, California. Additionally, data were collected through personal interviews conducted at the time of arrest with a subsample of persons arrested for drug charges. The arrest tracking file, Part 1, contains demographic information about the offenders, including criminal history and gang membership, as well as data on each arrest through final disposition, charges, and sentencing. The interview portion of the study, Part 2, provides information about the demographics and characteristics of drug users and dealers, criminal history and drug use history, current arrest information, and offenders' opinions about drug use, drug sales, police strategies, and the drug market.

Evaluation of a Hot Spot Policing Field Experiment in St. Louis, 2012 - 2014 (ICPSR 36129)

Released/updated on: 2017-12-07
Geographic coverage: Missouri, St. Louis
Time period: 2012-01-01--2013-10-01

The two central objectives of this project were (1) to evaluate the effect on crime of a targeted patrol strategy mounted by the St. Louis Metropolitan Police Department (SLMPD) and (2) to evaluate the researcher-practitioner partnership that underlay the policing intervention.

The study addressed the following research questions:

  1. Do intensified police patrols and enforcement in crime hot spots result in larger reductions in firearm assaults and robberies than in similar areas subject to routine police activity?
  2. Do specific enforcement tactics decrease certain type of crime?
  3. Which enforcement tactics are most effective?
  4. Does video surveillance reduce crime?
  5. How does the criminal justice system respond to firearm crime?
  6. Do notification meetings reduce recidivism?
  7. Does community unrest increase crime?
  8. Did crime rates rise following the Ferguson Killing?

To answer these questions, researchers used a mixed methods data collection plan, including interviews with local law enforcement, surveillance camera footage, and conducting ride-alongs with officers.

Evaluation of Camera Use to Prevent Crime in Commuter Parking Facilities within the Washington Metro Area Transit Authority (WMATA) Parking Facilities, 2004-2009 (ICPSR 32521)

Released/updated on: 2015-02-27
Geographic coverage: District of Columbia
Time period: 2004-01-01--2010-01-01

This study sought to identify what parking facility characteristics and management practices within the Washington Metro Transit Police (MTP) might create opportunities for crime, analyze those findings in relation to past crimes, and identify promising crime reduction strategies. The project consisted of three main research components: (1) identification of the magnitude of car crime in commuter parking facilities and possible strategies for prevention of such car crime; (2) identification and implementation of a crime prevention strategy; and (3) evaluation of the strategy's effectiveness.

In partnership with the MTP staff, the research team created a blocked randomized experimental design involving 50 matched pairs of commuter parking facilities in which a combination of live and dummy digital cameras were deployed, along with accompanying signage, at the exits of one randomly selected facility from each pairing. After a period of 12 months following camera implementation, the research team analyzed the impact of the cameras on crime occurring in and around Metro's parking facilities.

Evaluation of the Agriculture Crime Technology Information and Operation Network (ACTION) in Nine Counties in California, 2004-2005 (ICPSR 4686)

Released/updated on: 2009-05-01
Geographic coverage: United States, California
Time period: 2004-01-01--2005-01-01
The Urban Institute and Florida State University multidisciplinary research team employed a multimethod approach to evaluate the Agricultural Crime, Technology, Information, and Operations Network (ACTION) project. The goal of the research was to provide policymakers, practitioners, program developers, and funders with empirically-based information about whether ACTION works. Two paper-and-pencil, self-administered surveys -- one in fall 2004 and the second in fall 2005 -- were sent to samples of farmers in the nine ACTION counties in California. The researchers identified farms using lists provided by Agricultural Commissioners in each county. The survey instruments asked farmers about experiences with agricultural crime victimization during the 12 months prior to the survey. It also asked questions about characteristics of their farm operations and the activities that they take to prevent agricultural crime. Advance notice of the study was given to farmers through the use of postcards, then surveys were sent to farmers in three waves at one-month intervals, with the second and third waves targeting nonrespondents. The Fall 2004 Agricultural Crime Survey (Part 1) contains data on 823 respondents (farms) and the Fall 2005 Agricultural Crime Survey (Part 2) contains data on 818 respondents (farms).

This study examined the impact of technology on social, organizational, and behavioral aspects of policing. The present data represents an officer-level survey of four law enforcement agencies, designed to answer the following questions: (1) how are technologies used in police agencies across ranks and organizational sub-units? (2) how does technology influence organizational and personal aspects of police including - operations, culture, behavior, and satisfaction? (3) how do organizational and individual aspects of policing concurrently shape the use and effectiveness of technology? (4) how does technology affect crime control efforts and police-community relationships? (5) what organizational practices help to optimize the use of technology with an emphasis on enhance effectiveness and legitimacy?

Preparedness of Large Retail Malls to Prevent and Respond to Terrorist Attack, 2004 [United States] (ICPSR 21140)

Released/updated on: 2007-12-18
Geographic coverage: United States
The purpose of this project was to assess the level of security in large indoor shopping malls. The researchers administered surveys to the security directors of the nation's largest indoor retail malls. The researchers sent letters with surveys attached, to 1,372 security directors of enclosed retail malls across the country, which were at least 250,000 square feet in size. A total of 120 completed surveys were returned. The survey instrument was divided into the following nine sections: (1) Hiring Standards, (2) Training, (3) Security Budget, (4) Human Surveillance Strategies, (5) Access Control Plans, (6) Technological Enhancements, (7) Emergency Preparedness Procedures, (8) Relations with the Public Sector, and (9) Opinions about Terrorist Threat.
