“Unchecked Injustice” is based on 224 interviews with survivors and witnesses to abuses in Nairobi, Kisumu, Machakos, Migori, Nakuru, Kisii, Nyamira, Homa Bay, Siaya, and Makueni counties. The report documents how police used arbitrary and excessive force against protesters between March-July 2023. They shot directly into crowds with lethal weapons and less-lethal “rubber bullets,” fired tear gas into residential areas and schools, and carried out violent and abusive house-to-house operations, beating and shooting residents, killing at least 31 people. The Independent Policing Oversight Authority, which provides civilian oversight of the work of the police in Kenya, recorded that at least 67 were killed during this period.
