Commonwealth Games fudging

The 7.30 Report tonight reported on a few isues about the Games, including allegations of cover ups about doping, where a spokesperson for the Australian Anti-Doping Authority fudged the issue with a chllling example of doublespeak:

"I'm not avoiding the question, but I'm not going to speculate on the answer."

With all this information available to him why can't he move things on?
