Mr. Simon O'Brien:

I come back to the original point. Initially we were looking at the risks presented to our security. At the time we may have been under surveillance. In any risk assessment process one has to look at the range of threats across the building. One of them could have been being looked at through binoculars. One looks at all of these things to identify whether the potential risk is high, low or medium and how to respond. Therefore, when we get to the point of threat, of course, one says there could be a level of surveillance by another person or agent-----
