"The AR-15, which is the weapon used by the gunman at Robb Elementary, is designed to blow targets apart. It's a weapon built for war. And when fired into a human adult body, its bullets travel with such fierce velocity that they can decapitate a person or leave a body looking 'like a grenade went off in there,' as Peter Rhee, a trauma surgeon at the University of Arizona, told Wired. The carnage the weapon leaves behind has become a signature of school shootings and other mass shootings across the country."
