Security sector reform has in the recent past been a critical component of peace agreements in countries emerging from armed conflicts or political crisis. In Kenya, the Commission of Inquiry into the 2007/08 Post-Election Violence (CIPEV) established that Kenya’s security sector, particularly the police, bore the greatest responsibility for the violence. Subsequently, the police emerged as one of the major institutions for reforms. ‘How have security sector reforms, particularly police reforms, in Kenya developed since 2007 and how, and to what extent, have they been shaped by Kenya’s wider political transitions and SSR process during this period?’ The research aimed at investigating how the police reform process in Kenya has developed since 2007, and how the process has been shaped by Kenya’s wider political transitions and security sector reform processes in general. Using mixed methods research, we found that despite some progress, there is wider public perception that the reforms are yet to address reform priorities at the national level and still fall short of expectations of ordinary Kenyans. We argue that political power-sharing after the 2007 post-election violence facilitated police reform, while at the same time frustrated its implementation especially in instances where reform seemed to dis-empower political elites.
