The following is an excerpt from ALL THE WAY DOWN THE SLIPPERY SLOPE: GUN PROHIBITION IN ENGLAND AND SOME LESSONS FOR CIVIL LIBERTIES IN AMERICA

In December 1910, three London policemen investigating a burglary at a Houndsditch jewelry shop were murdered by rifle fire. A furious search began for "Peter the Painter," the Russian anarchist believed responsible. The police uncovered one cache of arms in London: a pistol, 150 bullets, and some dangerous chemicals. The discovery led to front-page newspaper stories about anarchist arsenals, which were non-existent, all over the East End of London. The police caught up with London's anarchist network on January 3, 1911, at 100 Sidney Street. The police threw stones through the windows, and the anarchists inside responded with rifle fire. Seven-hundred and fifty policemen, supplemented by a Scots Guardsman unit, besieged Sidney Street. Home Secretary Winston Churchill arrived on the scene as the police were firing artillery and preparing to deploy mines. Banner headlines throughout the British Empire were already detailing the dramatic police confrontation with the anarchist nest. Churchill, accompanied by a police inspector and a Scots Guardsman with a hunting gun, strode up to the door of 100 Sidney Street; the inspector kicked the door down. Inside were the dead bodies of two anarchists. "Peter the Painter" was nowhere in sight. London's three-man anarchist network was destroyed.
