Overview
Mapping Police Violence is a research collaborative project that tracks unreported police killings throughout the United States. The website was designed for the sole purpose of linking killings to where and when they took place. The data shown on the site is the most thorough documentation of people killed by police since 2013. It includes 1,131 known police killings, including 1,067 arrest-related deaths (according to Bureau of Justice Statistics definitions) as well as 64 unintentional, off-duty and/or in-custody deaths – that occurred in 2014. They also include information on 1,080 police killings in 2013, 1,131 in 2015, 1,129
police killings in 2016 and 1,147 killings in 2017. Significantly, the data on the site do not include killings by vigilantes or security guards.
Why is it significant?
Law enforcement agencies spanning the country often fail to provide even the most fundamental information about the lives of the victims in which they take. Although the newly signed Death in Custody Reporting Act requires this data be reported, it is unsure where or not police departments will actually adhere with this. The maps and diagrams on the site hopes to provide the answers we all need. The data will be utilized to unveil and provide accountability for police departments as part of the ongoing campaign to end police violence across the country. The creators of the site began with deaths tracked by the Burear of Justice Statistics, but discovered that they undercounted the victims, excluded location, and often did not include race.
