The school shooting outrage in Connecticut has united Americans in demanding an end to this scourge on our society.
But when it comes to identifying the right solution, the country is as divided as ever.
Some believe it's mostly a mental-health issue, and that more aggressive screening and intervention needs to be pursued.
Many also, or instead, blame easy access to firearms that seem to have only one purpose: mass murder.
Still others, including Wayne LaPierre, executive vice president of the National Rifle Association (NRA), blame violent video games and the broader media culture.
As with any complex problem, the answer isn't simple. Each nightmare, each perpetrator, is unique.
Certainly, more mental-health resources -- and tighter screening of those seeking to purchase weapons -- are both needed. And while we remain staunch defenders of the First Amendment, like many we recognize that nihilistic, violent video games are hardly beneficial to society.
We continue to call on Congress and the president to act quickly to ban assault weapons, high-capacity ammunition clips and certain kinds of bullets.
