Elizabeth Rosenthal (left), physician and science reporter for the New York Times, writes that the NRA's advocacy of "a good guy with a gun" in all of America's schools (which didn't stop the Columbine massacre) is based on the flawed principle that the answer to gun violence is more guns. Such an strategy hasn't worked in Latin American countries; instead, the U.S. would be better served emulating the gun control approach in Australia and some Latin American cities such as Bogotá, Colombia:
...I recently visited some Latin American countries that mesh with the N.R.A.’s vision of the promised land, where guards with guns grace every office lobby, storefront, A.T.M., restaurant and gas station. It has not made those countries safer or saner.
Despite the ubiquitous presence of “good guys” with guns, countries like Guatemala, Honduras, El Salvador, Colombia and Venezuela have some of the highest homicide rates in the world.
...In Guatemala, riding a public bus is a risky business. ...when bullets start flying, everyone is vulnerable: in 2010 the onboard tally included 155 drivers, 54 bus assistants, 71 passengers and 14 presumed criminals. Some were killed by the robbers’ bullets and some by gun-carrying passengers.
Scientific studies have consistently found that places with more guns have more violent deaths, both homicides and suicides. Women and children are more likely to die if there’s a gun in the house. The more guns in an area, the higher the local suicide rates. “Generally, if you live in a civilized society, more guns mean more death,” said David Hemenway, director of the Harvard Injury Control Research Center. “There is no evidence that having more guns reduces crime. None at all.”
After a gruesome mass murder in 1996 provoked public outrage, Australia enacted stricter gun laws, including a 28-day waiting period before purchase and a ban on semiautomatic weapons. Before then, Australia had averaged one mass shooting a year. Since, rates of both homicide and suicide have dropped 50 percent, and there have been no mass killings, said Ms. [Rebecca] Peters, [former director of the International Action Network on Small Arms], who lobbied for the legislation.
...Indeed, even as some Americans propose expanding our gun culture into elementary schools, some Latin American cities are trying to rein in theirs. Bogotá’s new mayor, Gustavo Petro, has forbidden residents to carry weapons on streets, in cars or in any public space since last February, and the murder rate has dropped 50 percent to a 27-year low. He said, “Guns are not a defense, they are a risk.”
