Armed body guards should in theory be given to any mwananchi. I have on many occasions hired policemen to guard my compound when I am present. To ensure no games, I usually insist on out of town policemen. I pay for the service and when its over, give each mwananchi a parting gift as I leave.
In fact I don't have to. The police should on their own assess the level of threat and danger against a given citizen and then take measures that it can to protect the person regardless of rank.
However in Kenya, "security" is the same as status. The more policemen you have following you and making trouble for wananchi the more "important" you are. Some MPs and senators need no security. They are in no danger. The same applies to some Ministers and so on. But they have "security" as a status symbol.
