Shame could control guns better than new laws

2. Many smokers had no shame either.

But we still had much success in eliminating public smoking because of the deaths it caused, both by the smokers themselves, and of those around them breathing the smoke.
The same thing can happen with deadly weapons. Make then publicly unacceptable. It took many long years and billions of dollars in advertizements to ban smoking in public, but it happened.

There is no reason to be armed in church, Target, K-mart, or even Wal-Mart, scooter fights not withstanding.
Feeling one has to be armed in public as a normal thing, is a symptom of paranoia. There is help.

Thinking nothing can be done because the gunners have no shame is a defeatist attitude. Change the public's perception, as happened with smoking and we can get the gun cause carnage under control.
