Why the fight against corruption is crippled by inadequately trained police

Yesterday, Water CS Simon Chelugui was being grilled by the police over the stalled Itare Dam Project budgeted at the cost of Sh19 billion. The issue of top government officials being arrested and questioned by the police has been the norm in this country since 2013. In the past few years, we have seen the Jubilee government intensify the fight against corruption with the goal of eradicating this vice completely. Many people in senior government positions have been dragged to courts to answer for cases tying them to corruption, money laundering, and tax evasion scandals. 

Well, we have had some successes and failures, with some people going to jail while others being let go by the courts. The criminal justice system in Kenya lets these suspects free because of lack of enough evidence.
