In 2011, guns were used to murder 8,583 people living in the U.S., according to the most recent FBI data available. Among those murdered by guns, there were 565 young people under the age of 18, and 119 children ages 12 or younger -- the latter number nearly equivalent to six Newtown mass shootings. And these figures include only homicides.8,583 gun-murdered Americans in a year = 9/11 every 3 months.
119 gun-murdered kids under the age of 12 = Sandy Hook every 2 months.
