My Lords, I got the impression while the noble Earl was speaking that the general public might have no real comprehension that they, too, have a part to play, and think that this is essentially something that can be left to the services. I am old enough to recall what we did just before the last war with the “Careless Talk Costs Lives” and similar campaigns. On the whole, those were remarkably successful. I am sure that no one wants to panic, but I believe that someone could examine how that was done. For example, people buy considerable quantities of certain chemicals. Every year, I buy two hundredweight —to use an old term—of a certain chemical for gardening purposes, although I will not mention the chemical. I was asked what I use it for. The noble Earl has mentioned a similar example. Actions like that could provide the public services with more information than they get now.
