Stop defending the indefensible.
Schoolchildren look out the window of their bus as they head back to school in Newtown, Conn., Tuesday, Dec. 18, 2012. Classes resume Tuesday for Newtown schools except those at Sandy Hook. Buses ferrying students to schools were festooned with large green and white ribbons on the front grills, the colors of Sandy Hook. At Newtown High School, students in sweatshirts and jackets, many wearing headphones, betrayed mixed emotions. Adam Lanza walked into Sandy Hook Elementary School in Newtown, Friday and opened fire, killing 26 people, including 20 children, before killing himself.
There is no defensible reason for civilians to own a Bushmaster .223-caliber rifle or other semiautomatic rifles, known more broadly as assault weapons.
This is essentially a military weapon, a version of the M-16, capable in some cases of shooting bullets at more than 2,000 feet per second. It does not belong in private hands, any more than M-1 Abrams tanks belong on Rockville Pike or mortars in the backyard.
Gun-owner advocates who point out that violent crime has fallen in recent years, in the absence of new gun controls, are correct. The link between guns and violence is not always clear-cut.
But the link between a certain kind of mass murder and a particular killing technology is clearer. It makes sense to reimpose strict limits on these assault weapons, including a ban on high-capacity magazines with more than 10 bullets each. These magazines have figured in several of the most heinous mass shootings in recent years, including the one that severely wounded Rep. Gabrielle Giffords, D-Ariz., in 2011. The Bushmaster is also a source of grief for Mexico, where it has become a favorite weapon of warring drug cartels.
In his remarks in Newtown on Sunday, President Obama noted that this was the fourth time in his presidency he has consoled a community grief-stricken by a mass shooting. He made clear he no longer wants to be simply the consoler in chief.
"We can't tolerate this anymore," he said. "No single law -- no set of laws can eliminate evil from the world, or prevent every senseless act of violence in our society. But that can't be an excuse for inaction. Surely, we can do better than this."
Yes, we can. We can start by locking up these killing machines. Obama endorsed an assault weapons ban when running for president in 2008, but in office he has been cautious. The loss of life in Connecticut demands a move from caution to action.
