Burt Prelutsky: “[S]omeone recently sent me what he called a tale of two cities, in which he compared Chicago to Houston. The things they had more or less in common was population (Chicago’s 2.7 million to Houston’s 2.15 million); median household income ($38,600-$37,000); percentage of blacks (38.9% to 24%); percentage of Hispanics (29.9% to 44%); percentage of Asians (5.5% to 6%); percentage of non-Hispanic whites (28.7% to 26%). The differences were that Chicago doesn’t have a concealed carry gun law, Houston does. Chicago doesn’t have any gun stores, Houston has 184. In spite of which, Chicago had 1,806 homicides in 2012, Houston had 207. Another difference is that the average January high temperature in Chicago is 31 degrees, 63 in Houston. From all of that, you would think the typical liberal would naturally conclude that, whatever else it does, global warming reduces the murder rate.”
