"The incident is a symptom of a problem more serious than terrorism: the lack of effective gun control in the U.S. As I have reported previously, between 1970 and 2007, a total of 3,292 people in the U.S. were killed by terrorists, resulting in an annual risk of one in 3.5 million. Almost all those deaths occurred on a single day, 9/11/01. In contrast, more than 32,000 Americans are shot to death every year, according to the Brady Campaign to Prevent Gun Violence. Of those, more than 11,000 people are murdered and almost 20,000 kill themselves. The U.S., which has more firearms per capita than any other nation, has rates of gun-related killings much higher than any other developed nation."
