Once again: "When seconds count . . ."

... the police are only minutes away." John Stossel:

The Cato's Institute's Tom Palmer, an early plaintiff in the D.C. gun case, told 20/20" he is alive today because he was carrying a handgun when he was approached on the street by some toughs. "They told us, 'We're going to kill you.' I showed them the business end of a pistol. They turned around, went away."

The four dissenting justices fear the Supreme Court's decision will unleash a flood of gun violence. Unlikely. "Criminals do not have a problem getting guns," Palmer reminded me.

It's law-abiding people who suffer when guns are banned. The victims of gun crimes are easy to count. What cannot be counted are the lives saved because would-be victims were armed. Palmer's confrontation is one of many that didn't make the news.

He asks, "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 make a crime report and take a picture of your dead body.

"They can't get there in time to save your life."
