I was looking at the FBI Expanded Homicide Data Table 11 and a few things stood out to me. There was a category that easily outpaced gang-related homicides that I believe is a key to the problem in the U.S. and guns: arguments. In 2011, over 3 times more people were shot and killed in an argument (1,948) than are shot and killed in gang violence (619). Argument killings outpaced killings that occurred during felonies (1,271) which included the categories of rape, robbery, burglary, larceny-theft, motor vehicle theft, arson, prostitution, sex offenses, narcotics, gambling and more. Argument killings were the single highest known cause of homicide. And this is one reason why I believe that more guns = more homicide, because people in the heat of emotion and rage cannot control their impulse to strike out. And when they have a gun, their ability to strike with lethal force is enhanced. We can't control whether people get into arguments. We can influence—as demonstrated by other countries—the weapon they reach for in the heat of one.
