The usual suspects keep calling for more gun control laws. But this idea that gun control is crime control is just a myth. The National Academy of Sciences reviewed dozens of studies and could not find a single gun regulation that clearly led to reduced violent crime or murder. When Washington, D.C., passed its tough handgun ban years ago, gun violence rose.
The press ignores the fact that often guns save lives.
It's what happened in 2002 at the Appalachian School of Law. Hearing shots, two students went to their cars, got their guns and restrained the shooter until police arrested him.
Likewise, law professor Glen Reynolds writes, "Pearl, Miss., school shooter Luke Woodham was stopped when the school's vice principal took a .45 from his truck and ran to the scene. In (last) February's Utah mall shooting, it was an off-duty police officer who happened to be on the scene and carrying a gun".
It's impossible to know exactly how often guns stop criminals. Would-be victims don't usually report crimes that don't happen. But people use guns in self-defense every day. The Cato Institute's Tom Palmer says just showing his gun to muggers once saved his life.
"It equalizes unequals,"Palmer told "20/20". "If someone gets into your house, which would you rather have, a handgun or a telephone? You can call the police if you want, and they'll get there, and they'll take a picture of your dead body. But they can't get there in time to save your life. The first line of defense is you."
