Programmers have created an interactive map documenting over 500 instances of police brutality nationwide since the 2020 George Floyd protests began.

Grown out of a megathread on the subreddit /r/2020PoliceBrutality, it was made into a Github repository with the goal of "assist[ing] journalists, politicians, prosecutors, activists and concerned citizens who can use the evidence accumulated here for political campaigns, news reporting, public education and prosecution of criminal police officers."
