I don't see the connection with crime rates and gun laws. There's probably 100 other reasons that someone commits a crime that don't have to do with gun laws. You can even see that gun homicide rates don't necessarily correlate either. Many states with high rates of gun ownership and lax laws have high gun homicide rates, but a lot of states with similar laws also have low gun homicide rates. The south in particular has the highest, whereas the northern midwest has the lowest. I would say that population density has more to do with crime and gun homicides than carry laws do.
