Since 1982, there have been at least 62 mass shootings* across the country, with the killings unfolding in 30 states from Massachusetts to Hawaii. Twenty-five of these mass shootings have occurred since 2006, and seven of them took place in 2012.
Of the 143 guns possessed by the killers, more than three quarters were obtained legally. The arsenal included dozens of assault weapons and semi-automatic handguns with high-capacity magazines. Just as Jeffrey Weise used a .40-caliber Glock to slaughter students in Red Lake, Minnesota, in 2005, so too did James Holmes, along with an AR-15 assault rifle, when blasting away at his victims in a darkened movie theater. In Newtown, Connecticut, Adam Lanza wielded a.223 Bushmaster semi-automatic assault rifle as he massacred 20 school children and six adults.
More than half of the cases involved school or workplace shootings (12 and 20, respectively); the other 30 cases took place in locations including shopping malls, restaurants, and religious and government buildings. Forty four of the killers were white males. Only one of them was a woman. The average age of the killers was 35, though the youngest among them was a mere 11 years old. (See Jonesboro, Ark., in 1998.) A majority were mentally troubled—and many displayed signs of it before setting out to kill. Make people pass a background check for goodness sake!
