A new study of gun violence published by the American Journal of Public Health found that states with greater levels of gun ownership tend to have higher rates of gun-related murder.
The study, conducted by Boston University professor Michael Siegel and coauthors Craig S. Ross and Charles King III, examines this relationship in all 50 states from 1981 to 2010. The researchers found that "for each percentage point increase in gun ownership, the firearm homicide rate increased by 0.9 percent."
The authors note that, though they can't prove a causal relationship between higher levels of gun ownership and homicide, "states with higher rates of gun ownership had disproportionately large numbers of deaths from firearm-related homicides."
Their findings echo past studies about the relationship between gun ownership and homicide, though Siegel, Ross and King look at the relationship over a larger window of time than previous research.
According to a fact sheet from the Harvard School of Public Health:
Our review of the academic literature found that a broad array of evidence indicates that gun availability is a risk factor for homicide, both in the United States and across high-income countries. Case-control studies, ecological time-series and cross-sectional studies indicate that in homes, cities, states and regions in the US, where there are more guns, both men and women are at higher risk for homicide, particularly firearm homicide.
A more localized 1993 study published in the New England Journal of Medicine, which focused on the most populous counties in Tennessee, Washington and Ohio, found that "keeping a gun in the home was strongly and independently associated with an increased risk of homicide."

President Obama Has Been Good To Them
Despite regular criticism of President Obama from the NRA and other pro-gun groups, Obama has actually <a href="http://www.time.com/time/politics/article/0,8599,2046592,00.html#ixzz1pDJ3yNPk" target="_blank">expanded gun rights</a> during his first term.

It Will Accessorize To Attract Women
Women remain a largely untapped demographic for the gun industry, which is why manufacturers have recently stepped up <a href="http://www.sfgate.com/nation/article/For-gun-industry-women-a-major-market-4267485.php" target="_blank">efforts to attract new female customers</a>. Apparently this <a href="http://www.gungoddess.com/ar-15-pink-stock-set/" target="_blank">pink assault rifle stock set (pictured) from GunGoddess.com</a> is one way the industry hopes to entice women to buy guns. "My intention with offering these products is to encourage women to discover the enjoyment they can get from shooting and the shooting sports, while at the same time not losing sight of the most important goal - taking responsibility for their own protection and learning critical self defense skills," Athena Means, owner of GunGoddess.com, wrote The Huffington Post in an email.

The Second Amendment Didn't Used To Apply To Individuals
While the Second Amendment does indeed say that "the right of the people to keep and bear arms shall not be infringed,” that was <a href="http://www.newyorker.com/online/blogs/comment/2012/12/jeffrey-toobin-second-amendment.html" target="_blank">historically interpreted as the right of militias to do so</a>, according to The New Yorker. It was not until a 2008 Supreme Court ruling, commonly referred to as the Heller decision, that the individual right to bear arms was guaranteed under federal law. <em>This slide has been updated to include additional information about the Heller decision.</em>
