Omollo: Those are the kind of question you discuss outside the docket. For now, this is a witness who has the ability to collapse a case if he has not already done that. The questions you are asking belong to investigation as opposed to prosecution. Bensudo if a smart prosecutor should distance herself from such a witness...that is not a witness. But your questions a valid. Perhaps you should consider a question on what his motive would be to tell the truth about his lies...may be he suddenly found the light.
On the contrary, that was the basis upon which recanting witnesses were compelled to testify. They basically came so the court can determine when they started lying. According to the OTP, they testified truthfully before they were corrupted and changed their stories. She has evidence of the corrupt witnesses trying to convince other witnesses to jump ship with promises of huge sums of money.
Now as you can see, the witness displays sketches of Ruto's house and then claims he was coached. There are some facts he may have come up with which he will find impossible to recant. If there is audio and video of the meetings (which I suspect there is) his new story may come apart.
The OTP simply wants to reach a point where the earlier statements are introduced in the evidence and form part of the body of evidence. By having witnesses declared hostile, the OTP then is free to cross examine them more aggressively and hopefully have them trip. For example the first witness was too eager to recant everything, he "recanted" what he had not said! That was a bullseye for the OTP that went unnoticed. It is such eagerness and excessive zealotry that will bring them down. All the OTP needs is to demonstrate that a particular witness is NOW lying for the earlier claims to be taken seriously. It would help if a motive is established - like money or promises of cash. That is where Walter Barasa and the evidence against him becomes crucial.
I am no longer convinced that TNA is interested in Ruto getting off. Why else is the OTP not so bothered about telephone and bak records of Ruto?
