In the wake of the shootings at Sandy Hook Elementary School in Newtown, Conn., that left 20 children and 6 school staff members dead, President Obama stated that "we're going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics." However, he did not provide any detailed proposals for what meaningful action should look like. So, we're asking you: What kind of meaningful action do you think the United States should take to prevent future mass shootings? The Op-Ed columnist Nicholas D. Kristof raised many important questions in his Opinion piece "Do We Have the Courage to Stop This?" Mr. Kristof writes: In the harrowing aftermath of the school shooting in Connecticut, one thought wells in my mind: Why can't we regulate guns as seriously as we do cars? The fundamental reason kids are dying in massacres like this one is not that we have lunatics or criminals - all countries have them - but that we suffer from a political failure to regulate guns. Children ages 5 to 14 in America are 13 times as likely to be murdered with guns as children in other industrialized countries, according to David Hemenway, a public health specialist at Harvard who has written an excellent book on gun violence. So let's treat firearms rationally as the center of a public health crisis that claims one life every 20 minutes. The United States realistically isn't going to ban guns, but we can take steps to reduce the carnage. Do you think we should tighten gun control laws, by requiring background checks for all gun purchases, or by banning high-capacity magazines that allow shooters to keep shooting without stopping to reload? Or, as some argue, do you think the problem does not lie with guns, but instead is about providing proper treatment for all those people with serious mental health problems? Do you agree with Mr. Kristof that gun violence is a "public health crisis"? Do you want the government to treat the issue of gun violence in a similar way to how it has treated automobile fatalities, by systematically introducing new regulations and technology, like seat belts and crash safety standards? Or do you think guns are protected by the Second Amendment, whereas cars are not?
