Execution it should be - putting the nation's security at risk just so that they can line up their pockets, MYK! They think their tumbos are more important than the security and defence of 40m Kenyans?
To fight corruption is not that hard: For corrupt engineers who have been asked to build a bridge,they should be asked to sit at the bottom of the bridge for a few hours on its opening as traffic passes overhead - esp bridge ya heavy trucks.
For this corrupt military procurement guys, put them in those aging Jordanian F-5 jets and ask them to fly them themselves.
For corrupt docs who use poor quality/expired medicine (actually these are poisons) they should be forced to take the drugs themselves.
