From the safety of my polluted perch in Beijing, I was thinking how much difference one year could make to gun control in the United States. In this short interval, Americans have stopped mourning in America and gone back to business as usual.

After the tragedy of Newtown, Connecticut, in which 20-year-old Adam Lanza gunned down 26 elementary school students and adults, there was nationwide grief, shock and anger, with many people calling for more gun control measures. The gun lobby, however, led by the National Rifle Association, called not for more controls but for more guns in schools in the hands of armed security guards. They claimed that gun control was the problem, not the guns.

In his 2013 State of the Union address, President Barack Obama devoted no less than five paragraphs to addressing the epidemic of gun-related deaths in the US. He did so while former House of Representatives member Gabriel Giffords, a near fatality in a shooting at a shopping center, was sitting with First Lady Michelle Obama and with other victims of gun violence. Obama called for a ban on both high-capacity ammunition clips and assault weapons, and for background checks on the buyer of any weapon. The result of all the angst and grieving: even a much weakened version of the president's call for background checks was killed by a Senate filibuster.

All that Obama could muster in the recent speech to Congress were two tepid sentences: "I have seen the courage of parents, students, pastors and police officers all over this country who say 'we are not afraid" and "I intend to keep trying, with or without Congress, to help stop more tragedies...." Yet as Giffords noted, it is Congress that is afraid of the gun lobby.

In the vacuum of congressional action, many states decided to act on their own. While there were some bright spots like the election of a pro-gun control governor in the National Rifle Association's home state of Virginia, the results favor less gun control. A mere 39 measures restricting gun control were passed in states mostly controlled by Democrats. But in states mostly controlled by Republicans, 70 measures liberalizing gun ownership became law.

Perhaps most ominously, in the swing state of Colorado where a shooting in a cinema left a dozen people dead, the fear that Giffords ascribed to Congress also extends to the state legislature. Last year, Colorado was one of the states to enact tougher gun control measures such as requiring background checks on any prospective gun buyer. Enraged, the gun lobby mounted recall campaigns that resulted in the ousting of two pro-gun control lawmakers and the resignation of a third.
