Drawing the wrong lesson from the tragedy in Aurora

Why can't people see that these attacks keep taking place where guns are banned?

A new bipartisan ad demanding a plan from the 2012 presidential candidates to stop gun violence features Stephen Barton, who survived the shooting massacre this summer at a Colorado movie theater.
The Demand a Plan ad is set to air nationally during the presidential debate Wednesday in Denver and is led by shooting survivors and the Mayors Against Illegal Guns group.
Barton was shot in the face and neck while attending a midnight screening of "The Dark Night" at a movie theater in Aurora. The shooter, James Holmes, killed 12 people and wounded 58 others.
In the ad, Barton delivers his demand sitting in an empty movie theater.
"So when you watch the presidential debates, ask yourself: Who has a plan to stop gun violence? Let's demand a plan," Barton says.
For debate viewers unfamiliar with Colorado geography, the presidential candidates will be debating about 10 miles from the Cinemark movie theater where the mass shooting occurred in July. . . .
