Please show a source for the graphics. I am on the same side, but I have an unpleasant suspicion that what is being shown is not factual. I’ve started a study of murder rate by county based on state records and it doesn’t match the mapping. It’s not ready for prime time, but I know enough to question the image. Here’s a link to my preliminary study - CA, AZ, NV and UT are done to my satisfaction. All other states are incomplete, or not even started.
