The so called "vetting" simply taught lessons to the bribe takers on what NOT to do. If you are a bribe-taker and still still banking your bribes then you missed the memo. Mpesa is suicide.
There are just few places where policemen still pick those coiled notes thrown by the roadside.... trusted civilian "consultants" now perform that role. I some places like the Kericho-Eldoret junction (Makutano), Likoni ferry, mai mahiu-Narok, Chavakali-Kapsabet etc there are civilians collecting the cash and handing it over.
A better system of transmitting the cash has been setup. With many running vehicles (thanks to leasing) never wonder what a dusty landcruiser hardtop from Hola is doing in Nairobi. Now that I have mentioned it, start noticing those police vehicles. The Kenya Police is just one large mafia whose main occupation is to collect money, keep some and pass the rest up the system. From before the money reaches The CS Internal security.
Each region (=former province) has a quota that must be met. Therefore all avenues have to be employed. If you are a young OCS dreaming of becoming an OCPD or higher and constantly fail to meet your "targets", you might as well drop the dream as you not only will never make that rank but face the real prospect of demotion following some cooked up case against you. That hapless Kavuludi won't help you. Thanks to Jubilee MPs Kavuludi was emasculated.
My point here is any case is as good as lost if the investigation is shoddy. Tobiko has failed in that he never cleaned up the system left to him by KANU stooges. Now that the window of opportunity has closed, there is no chance of any reforms in that sector.
Thuita may be guilty or not. We will never know. I gave up on that case when Wetangula was openly and shamelessly allowed by Marende to bribe MPs
