Britain's violent crime record is worse than any other country in the European union, it has been revealed.

Official crime figures show the UK also has a worse rate for all types of violence than the U.S. and even South Africa - widely considered one of the world's most dangerous countries.

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. One might think, too, of the McDonald’s massacre in San Ysidro, California, in 1984, where the Swat team waited for their leader (who was held up in a traffic jam) while 21 unarmed diners were murdered.

Rhetoric about standing firm against terrorists aside, in Britain we have no more legal deterrent to prevent an armed assault than did the people of Mumbai, and individually we would be just as helpless as victims. 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. Our image of an armed society is conditioned instead by America: or by what we imagine we know about America. It is a skewed image, because (despite the Second Amendment) until recently in much of the US it has been illegal to bear arms outside the home or workplace; and therefore only people willing to defy the law have carried weapons.

In the past two decades the enactment of “right to carry” legislation in the majority of states, and the issue of permits for the carrying of concealed firearms to citizens of good repute, has brought a radical change. Opponents of the right to bear arms predicted that right to carry would cause blood to flow in the streets, but the reverse has been true: violent crime in America has plummeted.
