This paper asserts that the rampant corruption in the National Police Service threatens the Security in Kenya. The impact of endemic corruption in Police Service leads to elevated levels of crime, terrorism, and police brutality. Since independence, the government of Kenya has long been using the police culture, philosophy, and organization structure in the Police Service based on the British colonial security system. Such security system has dominated the Kenya police service with oppression, police brutality, and disrespect for human rights. To address the rising security concerns, Kenya has made efforts in reforming the National Police Service (NPS), but there exists several barriers. The Kenyas vision 2030 identifies security and safety as the two key pillars for economic growth. Based on the police reforms in the US, Kenya police reforms should underscore the principles of professionalism, integrity, accountability, and respect for human rights. Addressing Kenyan security require police reforms that focuses on strong political will, reorganization and modernization of police service, capacity building, and create a police service oriented to meet the security needs of Kenyans.
