I’d have to see a reputable source on that statistic. The sense I get is places like Chicago, NY, Baltimore, other larger urban centers have some pretty strict firearms laws and still tend to have high homicide rates. Do those skew the numbers for the state?
As an example: Illinois may have lax state laws, but Chicago has strict gun laws, and lots of homicides. If you removed Chicago from Illinois statistics, how would that affect the state’s statistics
