The biggest problem I have with that chart is it only includes the 40 largest cities. The city I live in is in a deep red state and is run by a Republican mayor. Our homicide rate is 6.5 That’s enough to put us at #20. That’s worse than Chicago but 3/4 of a point but because we have a population that is a 1/3 the size of the cut-off for the chart we don’t get mentioned.
