Missing Voices is a collaboration between numerous NGOs that tracks police killings, enforced disappearances, and extrajudicial executions in Kenya.
The visualization firm OdipoDev, founded by designers Odanga Madung and Samer Costello, has created a data-driven story that displays their main figures (methodology page here). Missing Voices also contains a gallery of obituaries of every individual who's died at the hands of the police.
This is important work.
