Producing security in South Africa: continue the good job after the games are over

During the FIFA world football championships, South Africa has proven to be able to deliver security. A complete crackdown on crime, by placing a host of police officers on every street corner. Even South African citizens in Durban, Cape Town and elsewehere, admit that they feel secure now.
This raises a question: can't the south african government produce security after the games are over? Is there sufficient political will to continue the good job or will the government fall back to its old habits of corruption, self-pity and bureaucracy?
Delivering food and economic security to ALL its citizens, will attack the roots of economic crimes. An effective deployment of the available police force, patrolling its borders, and education will do the rest. There is no reason why South Africa can't become the civilized society that it once was, but now on a full democratic basis. Fully realizing its potential. The economic strength is there, as it is one of Africa's four strongest economies with a GDP growth in the regions of 4-5% annually.

If South Africa is NOT able to delivery security to all its citizens after the games are over, the opportunity to become a real African Growth Tiger are missed. And another lost decade looms where the brains are exported to more promising countries.
