The only way to stop a bad guy with a gun is a good guy with a gun.
It's a common refrain touted by gun rights advocates, who argue that using guns in self-defense can help save lives. But what is the actual number of defensive gun uses?
According to the Pew Research Center, 48 percent of gun owners say they own a gun mainly for protection. But for years, experts have been divided over how often people actually use guns in self-defense. The numbers range from the millions to hundreds of thousands, depending on whom you ask.
The latest data show that people use guns for self-defense only rarely. According to a Harvard University analysis of figures from the National Crime Victimization Survey, people defended themselves with a gun in nearly 0.9 percent of crimes from 2007 to 2011.
"The average person ... has basically no chance in their lifetime ever to use a gun in self-defense," he tells Here & Now's Robin Young. "But ... every day, they have a chance to use the gun inappropriately. They have a chance, they get angry. They get scared."
It's fine if you like firearms, but realize you ain't gonna save any lives with them.
