Mr. Simon O'Brien:

We are in the hands of what I am told by security experts. That test was not repeated although we tried to repeat it to see whether we would get the same response. With any security issue, there can be tests resulting in false positives and tests in respect of which one may be relying on someone else. Who knows? Even the security firm itself could have some thoughts on it. I have thought about every single aspect. Coming on the back of that, the fact that we could find in our inquiries no specific or detailed evidence of what line may have phoned in made it a very difficult test. It is absolutely right that the security experts have a view. That, on its own, could suggest an offence but I believe it was a case of very strong suspicion, probably stronger than that pertaining to some of the other threats, and probably harder to explain away. However, it was my judgment that I could not think that met the threshold of an offence being committed by any other person or agent.
