You were not there in person yourself either, Stu. By your own reckoning that makes you just as unqualified to tell us who gets it or who doesn't as the rest of us.

Anyone who can do what Abedi did is insane, a sicko. Lone in the sense that he did it alone. But we don't know whether he acted alone. Quite likely not. If the frequency of fatal accidents on our roads increases, we don't shrug and just say that accidents are isolated incidents caused by lone bad drivers. We try to find out what's going on and act accordingly, by making cars safer, by better driver training, lower speed limits maybe, stricter laws on using mobile phones etc. There's a worrying-high rate of suicides among young men. We try to find out why and face up to the issues. We need to know why we get terrorist incidents on our streets. Giving up by declaring that it's just lone sickos doesn't cut it. There's work to be done and a discussion to be had, otherwise we are doomed always to react and never to preempt. Neither does claiming that the only people who "get it" are the people who were there.
