My mistake. The NBC link says it aired on Dec 15th, so it’s not really news.
NBC is reporting that police are admitting that initial reports that Adam Lanza used four of his mother’s handguns in the shooting and that the semi-automatic rifle was in the trunk of his mother’s car. They continue that he tried to buy a semi-automatic rifle and was deterred by the waiting period gun law.
So guns laws worked in deterring Lanza, but somehow we need more laws. Thanks to one of my ever-vigilant ninjas for the link.
