It is Democrats in those States who are doing the vast majority of the murdering.
"According to the US Department of Justice, African Americans accounted for 52.5% of all homicide offenders from 1980 to 2008, with Whites 45.3% and "Other" 2.2%. The offending rate for African Americans was almost eight times higher than Whites, and the victim rate six times higher. Most homicides were intraracial, with 84% of White victims killed by Whites and 93% of African American victims killed by African Americans.[42][43][44]"
