So explains John Lott, in an opinion column for Foxnews.com. Not a surprising result. The McDonald v. Chicago amicus brief I wrote for the International Law Enforcements Educators & Trainers Association (and other law enforcement organizations, and criminologists) showed that after Chicago enacted its handgun ban, its violent crime rate rose sharply. Pre-ban, Chicago had a violent crime rate 1.12 times greater than the violent crime rate of the 24 other largest cities. (That is, Chicago’s violent crime rate was 12% higher than that of the 24 other cities.) Post-ban, Chicago’s crime rate soared immediately, and remained 67% higher than the other large cities. The possibility that Chicago’s sudden and long-standing deterioration compared to other large cities is less than 1 in 100,000. Details are presented at pages 17-22 of the brief, and the appendices.
