The Kenya Wildlife Service is an internationally celebrated conservation body at the forefront of the global fight against poaching. It has the backing of Western NGOs and celebrities, and has stabilised elephant levels in Kenya, in part thanks to the hard line it takes on poachers.The KWS has a "shoot to kill" policy. Armed rangers, trained and equipped by the British and US military, are authorised to kill any suspected poachers who set foot inside Kenya's national parks.But is there another side to this organisation? Investigating a string of mysterious disappearances and deaths in the communities around the country's national parks, VICE takes its findings to the very top of the organisation, culminating in a tense exchange with globally renowned conservationist Dr Richard Leakey.
