Murder With Impunity
June 20, 2018
The Washington Post collected data on more than 52,000 criminal homicides over the past decade in 50 of the largest American cities.
The data included the location of the killing, whether an arrest was made and, in most cases, basic demographic information about each victim.
Reporters received data in many formats, including paper, and worked for months to clean and standardize it, comparing homicide counts and aggregate closure rates with FBI data to ensure the records were as accurate as possible.
