The other point that I just wanted to address quickly is the point that the Minister raised around the police being able to respond quickly. We have seen a major change in the way these terror networks and often individuals—and we were a victim of this ourselves in this country—operate. You may get some terrorist cells that operate with a very, very high degree of sophistication. We saw the Twin Towers as a clear example of that, where you had individuals that were planted in the States years before, that went through genuine commercial pilot training, were accepted in the communities and the societies that they lived in, and then they flew commercial airliners into the Twin Towers—a lot of finance, highly organised, and a very sophisticated attack that rocked the entire world. But then you'll come back to a very basic terror attack where it might quite simply be an individual that is completely corrupted with an ideology, that gets in a truck and drives into a crowd of people.
