Life is speeded up. It used to be that when a hideous atrocity occurred people waited a day or two, even a week, before co-opting it into their political armoury. Now it happens while the smell of cordite is still in the air and before the blood has dried. There is a breathtaking shamelessness about it and a certain narcissism, if not outright solipsism and an eagerness to demand a sort of acquired victim status.
