John Lott, in "More Guns, Less Crime," explains that crime fell by 10 percent in the year after the laws were passed. A reason for the drop in crime may have been that criminals suddenly worried that their next victim might be armed. Indeed, criminals in states with high civilian gun ownership were the most worried about encountering armed victims.
In Canada and Britain, both with tough gun-control laws, almost half of all burglaries occur when residents are home. But in the United States, where many households contain guns, only 13 percent of burglaries happen when someone_s at home.
Two years ago, the Supreme Court ruled in the Heller case that Washington, D.C.'s ban on handgun ownership was unconstitutional. District politicians then loosened the law but still have so many restrictions that there are no gun shops in the city and just 800 people have received permits. Nevertheless, contrary to the mayor's prediction, robbery and other violent crime are down.
Because Heller applied only to Washington, that case was not the big one. McDonald v. Chicago is the big one, and the Supreme Court is expected to rule on that next week. Otis McDonald is a 76-year-old man who lives in a dangerous neighborhood on Chicago's South Side. He wants to buy a handgun, but Chicago forbids it.
If the Supremes say McDonald has that right, then restrictive gun laws will fall throughout America.
Despite my earlier bias, I now understand that striking down those laws will probably save lives.
