I believe that the notion that this officer could have been dealt with in a different manner, but was not because of her ethnicity, is an attempt to dodge the seriousness of the issue.
This is a senior police officer in possession of the most horrible images, failing to take appropriate action - and that is something that needs to be addressed regardless of ethnicity, which is clearly not relevant.
As I said, a wider investigation should be finding out how these images came into the possession of anyone - and appropriate punishments for their dissemination, an act which condones and encourages their creation, should be given as soon as possible.
This issue is not only about the dreadful and inexcusable professional misjudgement of a senior police officer, it is about the unforgivable damage and exploitation of innocent children.
