The headline says Shooting spree leaves six dead in Washington state.
They did note that "Local media reported that the suspect has a history of mental illness and a criminal past." One might suspect that this might account for the man's rampage.
But no, this is Reuters. We must be told that "The incident is the latest in a series of mass shootings over the last few years in the United States, which is estimated to have the world's highest civilian gun ownership rate, leading gun control advocates to push for tighter restrictions."
Do you suppose I'll live long enough to see Reuters report on massacres of civilians in places like Darfur and note that "this is the latest in a series of mass shootings by governments or criminals, leading self defense advocates to push for more arms for civilians"?
