"No I never met them. But I definitely saw them passing through going into the off-license, you know coming out and going upstairs - you know, because I could see their place because they live just up there and I can see them from my window over there, you know. But we didn't take any notice, you know, in and out, in and out, so suddenly this thing happened, we never guessed."

"Well as a toxin of a particular kind it could be blended into food or drink, it could be impregnated into clothes or other items, or it could be spread through an aerosol. At every time however the impact would be rather small and localised, requiring the terrorists to have a rather extensive network before they could spread it throughout the country."

"There were two schools of thought within the intelligence services. One was that London will become the centre of all the terrorist activities in Europe because of the sheer number of the various ethnic communities here. The other one was that, paradoxically, London will have an immunity from all these terrorist attacks, precisely because it is the place where all the terrorists organisation has sought refuge in the past. The answer, of course, is somewhere in the middle."
