Background reading for tonight's Dialogue, from the Pew Research Center:
"Several mass shootings this year have brought renewed attention to the issue of gun violence in America, and President Obama has again called for Congress to change the nation’s gun laws.
"But the increased spotlight on guns does not reflect the overall gun violence trend in the country. Although most Americans think the number of gun crimes has risen, the U.S. gun homicide rate has actually stabilized somewhat in recent years, according to a Pew Research Center analysis of death certificate data collected by the Centers for Disease Control and Prevention.
"Between 1993 and 2000, the gun homicide rate dropped by nearly half, from 7.0 homicides to 3.8 homicides per 100,000 people. Since then, the gun homicide rate has remained relatively flat. From 2010 to 2013, the most recent year data are available, the number of gun homicides has hovered between 11,000 and 12,000 per year."
