Westminster

‘On Friday noon, July the 20th, 1714,’ begins the small, perfect 20th-century novel The Bridge of San Luis Rey, ‘the finest bridge in all Peru broke and precipitated five travellers into the gulf below.’ In the coincidence of crossing the bridge at the same time, explains the writer, Thornton Wilder, these five seemed to have been assembled by pure chance. Or had they? He entitles this first chapter ‘Perhaps An Accident’. He spends the rest of his book tracing the lives of each until the moment when, in a twang of rope, fate hurled all together into the abyss. Thus is the reader’s interest engaged for the human histories that unfold. But Wilder, an American Christian humanist, falters in his rationalism.

In yesterday's Guardian, David Shariatmadari confronts the claim that Islam is an especially violent religion. The claim, he says, is undermined by the fact that jihadi terrorism is a very recent phenomenon. Yes, there is also the violence of empire-building in its history, but you could say this of Christianity too. ‘Aspects of Islamic teaching do indeed justify some kinds of violence. Islam isn’t a pacifist religion. But again, it has this in common with Christianity, Judaism and other world faiths.’ As I have said quite a few times before, it is simply wrong to say that Islam and Christianity have much the same view of war and peace. Judging from its founding texts, Christianity is a pacifist religion, for its founder rejected violence.

Stay safe, London. Stay safe, everyone. It’s nice, isn’t it, as a sentiment, which is just as well because it is the motto du jour of every celebrity who has added his or her mite to what passes as debate on the terrorist attack last Wednesday. And, my goodness, they all piled in: JK Rowling, Katy Perry, James Corden, Neil Gaiman; every man and woman of them, you’ll be pleased to hear, against this sort of thing, and urging us all – especially those not actually resident in London – to 'stay safe'. The other trope is that 'nothing will divide us', that this is what terrorists want – Stella McCartney et al. This is presumably for the benefit of those people whose reaction to the man from Tunbridge Wells is to go out and punch a Muslim.

Those charged with keeping Britain safe from Islamist-inspired terrorism have always been clear that it was a question of when, not if, there would be another attack as I say in The Sun this morning. The one thing that has surprised the security services about this attack is the age of the terrorist. Up to now, their focus had been on angry young people. No one was planning for a 50 something terrorist. Our way of life should not change in response to this terrorist attack. But there are things we can do to combat this threat more intelligently. The security services don’t have the manpower to follow everyone who appears on their radar as the Westminster attacker Khalid Masood did; it takes 12 people to keep one person under close surveillance.
