Richard Munday, in the London Times, observes that citizens of modern democracies are typically less safe in the event of terrorist attack today than they were a century ago in gas-lit London when policemen carried only a truncheon and ordinary citizens were allowed to own and carry weapons.

For anybody who still believed in it, the Mumbai shootings exposed the myth of “gun control”. India had some of the strictest firearms laws in the world, going back to the Indian Arms Act of 1878, by which Britain had sought to prevent a recurrence of the Indian Mutiny.

The guns used in last week’s Bombay massacre were all “prohibited weapons” under Indian law, just as they are in Britain. In this country we have seen the irrelevance of such bans (handgun crime, for instance, doubled here within five years of the prohibition of legal pistol ownership), but the largely drug-related nature of most extreme violence here has left most of us with a sheltered awareness of the threat. We have not yet faced a determined and broad-based attack.

The Mumbai massacre also exposed the myth that arming the police force guarantees security. Sebastian D’Souza, a picture editor on the Mumbai Mirror who took some of the dramatic pictures of the assault on the Chhatrapati Shivaji railway station, was angered to find India’s armed police taking cover and apparently failing to engage the gunmen.

In Britain we might recall the prolonged failure of armed police to contain the Hungerford killer, whose rampage lasted more than four hours, and who in the end shot himself. In Dunblane, too, it was the killer who ended his own life: even at best, police response is almost always belated when gunmen are on the loose. …

The Mumbai massacre could happen in London tomorrow; but probably it could not have happened to Londoners 100 years ago.

In January 1909 two such anarchists, lately come from an attempt to blow up the president of France, tried to commit a robbery in north London, armed with automatic pistols. Edwardian Londoners, however, shot back – and the anarchists were pursued through the streets by a spontaneous hue-and-cry. The police, who could not find the key to their own gun cupboard, borrowed at least four pistols from passers-by, while other citizens armed with revolvers and shotguns preferred to use their weapons themselves to bring the assailants down.

Today we are probably more shocked at the idea of so many ordinary Londoners carrying guns in the street than we are at the idea of an armed robbery. But the world of Conan Doyle’s Dr Watson, pocketing his revolver before he walked the London streets, was real. The arming of the populace guaranteed rather than disturbed the peace.

That armed England existed within living memory; but it is now so alien to our expectations that it has become a foreign country.
