Best of luck backing up the claim that CCL holders are responsible for 10% of all murders. Don't forget your sources

The State of North Carolina is home to roughly 9.38 million people as of 2009. Of those residents only 228,072 hold a valid concealed carry permit according to the latest figures released by the North Carolina Department of Justice, figures which reflect the applications since December 1995 when the state began issuing permits. That equates to roughly 2.4% of the population that is legally allowed to carry a concealed firearm. As an interesting side note, those 228,072 permit holders come from an applicant pool of 399,268 which indicates that only about 57% of applications result in a permit.
In the year 2009 the FBI reported that murder and manslaughter (illegal acts where a person died) was committed at a rate of approximately 5.3 deaths for every 100,000 people in the state of North Carolina. This works out to about 497 deaths per year (using the population for 2009). Statistically the population of concealed carry permit holders should fall in line with this criminal death rate, and so we should expect no less than 12 criminal deaths in the year 2009 alone. However, the New York Times was only able to dredge up 10 such deaths (murders and manslaughter combined), and that was only accomplished by combining the last five years together. While we would expect 2% of the population to be responsible for 60 deaths over 5 years, in reality they are only responsible for 10.
