Columbine, Virginia Tech, Sandy Hook, and now, a community college in Roseburg, Ore. One after another, mass shootings have horrified the nation, stoking debate about the availability of legal guns and anguish over the inability of society to keep weapons out of the hands of seething killers.

But such rampage killings are not the typical face of gun violence in America. Each day, some 30 people are victims of gun homicides, slain by rival gang members, drug dealers, trigger-happy robbers, drunken men after bar fights, frenzied family members or abusive partners. An additional 60 people a day kill themselves with guns.

In Chicago alone in September — the city’s deadliest month in recent years — there were 57 homicides, most by gunfire, and 351 were shot and wounded. In total, counting suicides, 33,636 people in the United States were killed by firearms in 2013, according to the latest federal data.

“Mass shootings focus the public’s attention,” said Garen J. Wintemute, director of the Violence Prevention Research Program at the University of California, Davis, School of Medicine. “But we lose on the order of 90 people a day to firearms. We need to keep our eyes focused on the larger picture.”
