If the maps had been true, it would still not mean much. The Democrats are mostly urban, and the Republicans mostly rural. Crime is a lot more prevalent where people actually live, and probably a lot more likely to get reported where there are enough people to make it difficult to hide. There is no shortage of things that appear correlated on the map because they correlate with population.
However, in this case the maps look nearly identical because they deal with nearly the same data. Both are electoral maps, with the bottom just retitled.
