Citing murder rates (and ignoring other crimes) is one of the preferred tactics of people who want to say that big cities have low crime rates.
Police in big cities go after big crimes like murders, but tend to ignore "lesser" crimes, so as a result, gangsters and other career criminals stick to those lesser crimes, and generally do a lot more of them.
