单选题 Hundreds of thousands of American mothers descended on Washington and about 60 other U.S. cities yesterday to voice their support for stricter gun laws, making one of the country"s biggest demonstrations for many years.
The Million Morn March was focused on the capital, where a huge crowd of women, along with large numbers of men and children, gathered to mark Mothers" Day on the Mall, the green strip which leads to the Capitol building housing Congress. At the other end, below the Washington Monument, about 2,000 people calling themselves the Armed Informed Mothers staged a counter-protest against gun control.
President Clinton threw his weight behind the Million Mom March, holding a morning reception on the lawn of the White House for the rally"s leaders and the mothers of children killed by guns. "One of the things your mother teaches you when you grow up is that an ounce of prevention is worth a pound of cure," he told the crowd. But he pointed out that a string of gun-control measures had been stalled in congress for more than a year by the opposition of the gun lobby.
Violent crime has been falling in the U.S. for eight years, but the impact of firearms remains far higher than in other modern industralised countries. Every year 32,000 Americans—including 12 children and teenagers each day—die from gunfire through murders, accidents and suicides. Among the speakers at the gun-control rally in Washington were three women whose daughters died in the Dunblane massacre. Those murders triggered the Snowdrop Campaign, which eventually led to a ban on handguns in Britain.
Before the rally one of the Dunblane mothers, Allison Crozier, said she believed that the Million Morn campaign could ultimately outweigh the entrenched power of the gun lobby. "There are more mums who want something done. We did it in Scotland, they can do it here if they just stand up and do something about it," she told the BBC.
The counter-rally may have been tiny by comparison, but the progun demonstrators represent a powerful constituency. According to a survey published yesterday, 45% of U.S. households own a gun, and one in four Americans has been threatened with a gun. The gun-control lobbyists want child-proof trigger locks to be mad compulsory, and a 72-hour "cooling-off periods" for would-be buyers at weekend gun shows. Their opponents say those restrictions are only the first step towards a total ban.
One of the Armed Informed Mothers coordinators, Debra Collins, said her life was saved 16 years ago when she used a gun to defend herself against her violent ex-husband. "Thank God, my firearm was unencumbered by a trigger lock," she said. Organisers of the Million Morn March hoped that the turnout nationally would top a million. The final figure was unclear yesterday afternoon, but May Leigh Blek, one of the movement"s founders, said enough people had shown up to put gun control on the legislative agenda in congress. She said: "I hope when legislators see so many mothers, it will give them the courage to do the right thing."
