Assessing the Impact of Plea Bargaining on Subsequent Violence for Firearm Offenders, Maryland, 2015-2019 (ICPSR 39244)

Released/updated on: 2025-01-16

Geographic coverage: United States, Maryland

Time period: 2015-01-01--2019-01-01

The purpose of this study was to assess how patterns of prosecution and plea bargaining in firearms cases shape subsequent case and defendant outcomes. Drawing on recent work (Johnson and Larroulet, 2019), the researchers developed measures of plea bargaining discounts and examined their effects on sentencing and recidivism for firearms-involved offenders. To do so, the investigators [1] analyzed unique data collected by the Client Legal Utility Engine (CLUE), a web-scraped database of court records for all criminal cases in the State of Maryland for a cohort of defendants charged with firearms-involved crimes in district and circuit courts between 2015 and 2019; [2] generated estimates of the average distance traveled in charge bargaining, or the magnitude of average sentencing discounts in gun cases in Maryland by comparing expected sentences based on the original filed charges to the final charges at conviction; and [3] explored the association between plea discounts and recidivism, measured by the defendant coming back into the criminal court system on new criminal charges. The resulting dataset includes information on criminal case processing outcomes for firearms-related cases processed in Maryland district and circuit courts for the time period 2015-2019.

A Comprehensive Assessment of Deadly Mass Shootings, 1980-2018, United States (ICPSR 38482)

Released/updated on: 2022-09-29

Geographic coverage: United States

Time period: 1980-01-01--2018-12-31

As deadly mass shootings constitute a pressing concern for Americans, the database was created to assess features and trends in all deadly mass shootings in America between 1980 and 2018. In these data, mass shootings encompass all incidents with four or more gunshot fatalities, not including the shooter, within 24 hours. Open source media reports as well as official police and court records were used to code and verify details of mass shooting incidents. The data include information on public deadly mass shooting incidents, as well as all the other deadly mass shootings that occurred over this period (e.g., those that happened in private spaces among family members, and those that occurred in public spaces but were part of another criminal event). In all, the database contains information on 719 incidents that occurred in both public and private spaces between 1980 and 2018.

Detecting Fentanyl and Major Players in Darknet Drug Markets by Analyzing Drug Networks and Developing a Threat Assessment Tool, Global, 2020-2022 (ICPSR 39131)

Released/updated on: 2025-09-25

Geographic coverage: Global

Time period: 2020-01-01--2022-01-01

This study conducted both qualitative and quantitative analysis of scraped data from multiple Darknet marketplaces. The objective was to gain an understanding of fentanyl sales and trust in vendors in order to build a threat assessment tool. The marketplaces in the data include Versus, Cartel, ASAP, Tor2Door, ViceCity, and AlphaBay. Variables include product description/listing, category of products, price of product, amount per sale quantity, quantity available for sale, date vendor registered for the site, date last active on the site, vendor description, various vendor ratings and scores, and vendor/product feedback messages.

Preventing and Controlling Corporate Crime: The Dual Role of Corporate Boards and Legal Sanctions, United States, 1996-2013 (ICPSR 37463)

Released/updated on: 2021-04-29

Geographic coverage: United States

Time period: 1996-01-01--2013-01-01

This project consists of secondary analysis material (syntax only, no data). The original study that the material pertains to examines two distinct but related types of corporate crime prevention and control mechanisms--one that rests on firm governance (specifically, the Board of Directors) and the other on formal legal interventions. Specifically, the study examines whether (ceteris paribus) firms with more gender diversity on their boards are less involved in offending than firms whose boards are less diverse and whether changes in board diversity over time affect firm offending patterns. Of additional interest is how firms respond to legal discovery and punishment.

Do they change their governance structures (i.e., become more diverse) due to formal legal discovery?

Are firms generally deterred from reoffending (recidivism) when discovered or does deterrence depend on the government's response to offenders?

In particular, are certain regimes (criminal, civil, or regulatory) more successful at crime control than others?

Relevant data are collected from a variety of secondary sources, including corporate financial, statistical, and governance information. These data are then linked to cases of corporate offending (accounting fraud, bribery, environmental and anti-competitive) for 3,327 US based companies between 1996 and 2013.

Analyses-NIJ-5.21.2019--2-.do: Syntax (Stata) used to create type of offense count; domain of processing (civil, criminal, regulatory); offense distribution (by corporate year), female board membership (count and percent); Reoffending (by enforcement type and governance characteristics).

Racial Disparities in Virginia Felony Court Cases, 2007-2015 (ICPSR 38274)

Released/updated on: 2022-01-27

Geographic coverage: United States, Virginia

Time period: 2007-01-01--2015-12-31

Research examining racial disparities in the court system has typically focused on only one of the discrete stages in the criminal process (the charging, conviction, or sentencing stages), with the majority of the literature focusing on the sentencing stage. The literature has thus largely ignored the key early decisions made by the prosecutor such as their decision to prosecute, the determination of preliminary charges, charge reductions, and plea negotiations. Further, the few studies that have examined whether racial disparities arise in prosecutorial charging decisions are rarely able to follow these cases all the way through the criminal court process. This project sought to expand the literature by using a dataset on felony cases filed in twelve Virginia counties between 2007 through 2015 whereby each criminal incident can be followed from the initial charge filing stage to the final disposition. Using each felony case as the unit of analysis, this data was used to evaluate whether African Americans and whites that are arrested for the same felony crimes have similar final case outcomes.
