Olympics torched

Following some of the scenes witnessed during last year's Beijing torch relay in cities including London and Paris, the IOC has apparently decided to scrap future torch relays outside the country hosting the Games. Is this a wise decision? From a PR perspective in particular, surely the move makes great sense? Does what happened in 2008 highlight the risks of torch relays and the problems associated with managing them? Are host country torch relays that much easier to control? Can the potential appropriation of the Olympic Games by unrelated groups therefore be prevented? Or are we now seeing the IOC's response to a situation they failed to control and thus reflected badly upon the organisation? Is isn't it naive to assume that the same thing won't happen again? Aren't the management challenges just as great and intense? And isn't the move counter-productive, denying a vast majority of the world's population any access to the Games other than through television?
