The closest to that description I know if is the divided cites of El Paso, Texas and Ciudad Juárez, Mexico. Twin cities, similar population demographics, separated by a national border, which is about as good of a seal as screen door on a submarine. For all this, hat tip to Michael Bane, PJ Tattler and Dave Kopel of the Second Amendment Project.
Mexico has draconian gun control. Researcher Dave Kopel notes that possession of firearms above .22 caliber is practically prohibited, though there is a second set of rules for the wealthy. Mexico also requires registration for all civilian gun owners, and federal and state governments actively discourage firearms ownership.In my world, if you were to divide an American city, say Chicago, and set up these conditions, it would be unethical, because you'd be condemning so many of the people without guns to die.
More than 1,300 people have been killed in Juárez this year, and more than 8,600 have been killed since 2008 when a war began between the Juárez and Sinaloa drug cartels.
Meanwhile, here in Texas:
- Law-abiding citizens can walk into a gun store, buy a gun, and walk out with your purchase.
- Law-abiding citizens can carry concealed handguns in public.
- Concealed carry licensees are exempt from the NICS background check, because a FBI background check is part of getting their carry license.
In 2011 to date, sister city El Paso has experienced 15 homicides.
Putting it another way, it would take El Paso criminals about 50 years to catch up to the Juárez death toll January – July 2011.
