Kenyan police are ranked as the third most corrupt in the world.
Kenya ia at No.3 amongst the most corrupt police forces in the world. According to a recent survey report of Transparency International, the 92 percent civilians of Kenya ranked their police as the most corrupt and many of them have paid a bribe to their police during the last 12 months. Civilians are bribed into paying police for access to various services, like Customs, healthcare, education, police, registration and permits. They paid a bribe even on utility services.
Kenyans no more likely to dope than Europeans or Americans, of course. Especially Kenyan policemen like Kamworor or Rudisha.
