Yes, it is.
The point I was trying to make earlier, perhaps not very eloquently, was that it's just the tip of the iceberg. Those people who went “external”, if you like, and went to the media are taking a tremendous risk. It's a last resort. Research indicates that only 1% or 2% of whistle-blowers resort to going out to the media, even when everything else has failed.
For every story you read in the media, you can say there are probably another 50 that are similar that we'll never hear anything about because the whistle-blowers get crushed into silence.
