Texas is one of the few states that tracks crimes committed by concealed carry weapon permit holders. In Texas, the permit is called a concealed handgun license, or CHL.
The Texas Department of Public Safety has filed annual reports of the convictions of CHL holders from 1996 through 2011. They wait two years to obtain final conviction information before publishing the totals.
The number of CHL holders that commit murder or manslaughter is remarkably low. From the DPS reports for 1996 through 2011, the number of murder and manslaughter convictions for CHL holders totaled 30 over the 16 years.
