I think the general comment I would make is this: organisational blunders or corruption do not necessarily imply that the people involved are incompetent or evil. Sometimes all it takes is a set of competing but influential pressures that shift internal processes; like, for instance, a Government that attempt to direct a law-enforcement organisation to suit its political aims. This can induce a shift in the perspective people within the organisation take toward incoming information, in the way they define their goals, and in the way they interact with external bodies such as the media.
It seems to me that this type of distortion is exactly what has happened with Mick Keelty and his AFP. The institution requires reform and this probably includes refreshing the culture from the top, but we shouldn’t lose sight of where the problems originated – and in this, the segment on the Madrid bombings is very informative.
