From The Nation:
When Adam Lanza entered Sandy Hook Elementary School on Friday, December 14, inexplicably bent on ending as many lives as possible, he was carrying a Bushmaster AR-15 assault rifle and several high-capacity magazines. Sadly, this isn’t the first time the country has had to deal with the aftermath of a horrific shooting spree, nor is it the first time we’ve encountered an AR-15 in this context: only days earlier, it was the weapon of choice for a shooting at an Oregon mall that killed two people. Five months earlier, it was used by James Holmes in an attack that wounded fifty-eight people and killed twelve in an Aurora, Colorado, movie theater. And several years before that, a man and his teenage accomplice used a Bushmaster AR-15 to terrorize the Washington, DC, area with a series of random shootings.
Although it is not yet clear where the Bushmaster AR-15 used by Lanza (and registered to his mother) was purchased, the model is familiar to many Walmart shoppers. It’s on sale at about 1,700 Walmart stores nationwide, though the retail chain pulled the weapon from its website early this afternoon. While last week’s deadly rampage in Connecticut has finally and unmistakably highlighted the madness of making these weapons so readily available, it’s a concern many people with a Walmart in their community have been trying to address for much longer.
