The National Police Foundation, in partnership with the Major Cities Chiefs Association (MCCA) and law enforcement advisors, developed an online data collection tool where agencies entered information about all officer involved shooting (OIS) from 2015-2017, including detailed data on the officer(s) involved, the subject(s) who were present and fired upon, and the location(s) where the incident took place in near-real time.
This project involves analysis of the data collected through these efforts, focusing on critical issues in OIS incidents. First, we are analyzing detailed data on subjects, officers, and locations involved in OIS incidents. Next, we are describing OIS incidents from the initiation to the conclusion of the call, and analyzing whether there are factors that predict certain types of outcomes such as injuries and death. Third, we are categorizing and analyzing agencies’ investigatory and accountability responses to these events. Fourth, we are investigating the quality and scope of data available to and released by police agencies. Following this research, we will prepare and release publications that document our findings for researcher and practitioner audiences, as well as present findings during researcher and practitioner conferences. Our database is the first of its kind in the U.S. in covering all officer-involved shootings in a large sample of major cities.
During this project, we are auditing a complete set of 2015-2017 OIS data from over 50 major city agencies that will allow for analysis of four issues:
The fourth research question uses data from the over 300 items included in the OIS data collection tool, as well as information provided by agency points of contact about the availability of data elements, to determine which types of information are not commonly collected by participating agencies. We spent additional time and resources going back to agencies to try to ensure that we have the most complete data possible, and have captured information as to why certain agencies do not provide all variables, or cannot provide specific types of responses. For instance, some agencies are required to discard information about citizen complaints about an officer after a certain period of time due to union contracts. Documenting these data gaps will illustrate the barriers to knowledge about OIS incidents that currently exist among police agencies.
This project is funded fully by the Laura and John Arnold Foundation, and is made possible through collaboration with the Major Cities Chiefs Association.
