On March 4, 2021, New York City’s civilian police oversight group released a database of complaints made against current and former NYPD officers.
The official data can be found on the NYC website: https://www1.nyc.gov/site/ccrb/policy/MOS-records.page
The report is fantastic, but it's currently in a form that makes it very hard to aggregate or do statistical analysis on the data.
This project scrapes the backend data out of Microsoft Power BI, and outputs it into CSV for ease of use. It uses the same data endpoint the official UI does, and only has access to the same public information the official report does.
