Isn't why they were found them (IFMIS) and their money frozen. Imagine a paper system.
First, we are not entirely clear on exactly how much was stolen, let alone frozen. We started with Sh. 791, and last we heard it was Sh. 2B.
Second---and this is the most important part---the issue in Kenya has never been one of "finding" who stole what or how much they stole. Anglo Leasing, Goldenburg, Triton, ..., Chicken-gate: the names and numbers are all out there.
Another case where you don't understand the issue.
The fundamental problem is that of stopping such theft, not whether it can be detected. Whether the detection is by computer or by paper-and-pencil is completely irrelevant to that. Let me try and put it in an even simpler way: if people know they can steal and get away with it, then merely "finding" them is completely unhelpful, and the techniques and tools used in the "finding" do not change that.
