America's gun outrage: 276 people killed or wounded a day
By now you will have heard of Major Nidal Malak Hasan, the US Army psychiatrist who shot 13 of his colleagues dead and wounded 31 inside the army's largest base, Fort Hood in Texas, last Thursday.
Taryale Petter, John Herman, Jason Rodriques and Marcus Gonzalez are names you may not know.
Taryale was only 15 years old. Early on Friday morning, aboard his Philadelphia school bus, he pulled a handgun from his bag and shot another child.
Hermann, a Minnesota cop, on Tuesday shot dead a man who ran over a plastic traffic cone in a car park.
On Friday morning, Rodriquez, 40, walked into the Florida engineering consultancy from which he had been sacked and opened fire, killing a young father and wounding five others.
Gonzalez, 29, who was jilted in love, shot dead four people on Wednesday in the North Carolina town that inspired fictitious Mayberry–the almost crime-free, one-traffic-light town, inspired by the 1960s Andy Griffith Show.
There are more, a lot more, from the past week.
