When bad things happen with guns, the desire to ban guns is to take away guns is understandable. But doing that can often make problems worse.
For example, it might seem obvious to protect people by banning guns in areas. But law-abiding citizens, not those intent on committing terrorist acts, obey these bans. Instead of making places safer, disarming law-abiding citizens leaves them as sitting ducks. With just one single exception, every public shooting since at least 1950 in the United States in which more than three people have been killed has taken place where citizens are not allowed to carry guns.
This isn't random. If it were, 98 or 99 percent of the attacks would occur in areas where people are allowed to carry concealed handguns for protection. Yet, all these attacks are squeezed into the tiny areas where guns are banned.
Take the Aurora, Colo. tragedy. There were seven movie theaters showing the premiere of the Batman movie within a 20-minute drive of the killer's apartment. Only one banned guns, posting signs warning permit holders that their guns weren't allowed. Yet, the killer didn't go to the theater that was closest to his home. Nor did he go to the largest theater. He went to the single one where he didn't believe that others would be able to protect themselves.
There is a simple way of understanding this point. If a violent criminal were ever stalking you or your family, would you put a sign in front of your home announcing that you didn't own a gun? Probably not. Yet, even though no one puts up those signs in front of their homes, we put up those signs on all sorts of other areas.
