If they are about knowing and advising on everything and anything, then what are the other agencies there for e.g. CBK, CID, KSB, Treasury, KRA, ama kazi yao ni kupanguza watu wa NIS jasho?

That was a good one.

OK, NIS is to collect intelligence, analyse it and advise the GoK.

These other "spoilt fattened kids" called CBK, KSB etc are to come up with POLICIES from the intelligence and see the policy been effected.

NIS is not C.I.D. NIS cannot arrest you because they are not police. They are INTELLIGENCE harvesters and analysers. Right now they should have their people allover COMESA countries collect intelligence on this sugar thing, so as they can advice KSB and Min. of Agric. on the way forward after expiry of those COMESA whatevers.

That is what i think the relationship between N.I.S and the other bodies should be.

You ASK yourself if all this parastatals have intelligence departments, how would it be. They can have enforcement and inspectorate departments, but not INTELLIGENCE.

When data is collected/intercepted, analysed/interpreted, then, you have intelligence. Which any organization can do and use to their benefit i.e. corporate espionage. So CID should have intelligence. So, then, dumping of sugar is something KSB and CID should handle. If it was being done by foreign entities intent on sabotaging Kenya's sugar industry/ and economy by extension then, we bring in NIS.
So, the question should be, is this being done to sabotage Kenya economically(I don't think so), it is just a cartel of greedy nationals who can be investigated and apprehended by Police/CID.
