“Most gunmen are smart enough to know that they can kill more people if they attack places where victims can’t defend themselves. That’s one reason why 98 percent of mass public shootings since 1950 have occurred in places where citizens are banned from having guns.
“The national media tend to ignore case after case of mass public shootings being stopped by armed private citizens. Just a couple of days before the synagogue shooting in Pittsburgh a concealed handgun permit holder stopped an alleged killer who was shooting blacks at a Kroger grocery store in Louisville, Ky.
“National media outlets such as ABC and NBC covered the attack, noting that the alleged gunman told another white man that: ‘Whites don’t kill whites.’ It sounded as if the gunman was merely reassuring a bystander that he had nothing to worry about. But reporters left out the crucial first part of the quote. The killer said: ‘Don’t shoot me. I won’t shoot you. Whites don’t shoot whites.’ The other white person was pointing a permitted concealed handgun at the killer.” – John Lott Jr. in How Gun-Free Zones Invite Mass Shootings
