You really have genocidal thinking.
It actually simple - civilize these people
Invest in west pokot - build infrastructure like roads, schools, churches.
Improve their livestock - send vets and drill boreholes.
Sending the police to people eating cobra is waste of time - they will never subdue pokot
Send KDF to go drill boreholes - enough watering points - and build cattle dips - give them free vet medicine - and in few years their cattle will survive - and they will stop risky cattle rustling trade - and focus on other things.
Pokots is bigger phenomena as desertification intensifies in Africa sahara - it affecting countries from senegal all the way to Lamu - as pastoralist - move from sahara into green areas - and inevitably conflict occurs.
The lapset project should be seen as long term solution to dealing with northern kenya - it may not be economical - but we need those roads - to open up these areas for civilization - and move savages from cattle - to new economic activities - like minning, tourism and such - irrigation farming.
I know a thug who used to hire Fielder. He'd drive to Rumuruti and harvest about 30 heads of goats, and bring them back to Kiamaiko.
Another alternative would be unleashing tsetse flies down there. Decimate all stock, drive a few into extinction while others innovate. But there's so little they can do under the hostile weather and terrain
