Mother Jones magazine claims to have produced its own study of all public shootings in the last 30 years and concludes: "In not a single case was the killing stopped by a civilian using a gun." YOU SAID, NO ONE WAS KILLED. MY QUESTION: HOW COULD YOU POSSIBLY KNOW CIVILIANS DID NOT HELP, AS NO ONE WAS KILLED OR SHOT? YOUR LOGIC DEFIES COMMON SENSE, BUT I GUESS THAT IS WHAT THIS DISAGREEMENT IS ALL ABOUT. THE FOLKS AT MOTHER JONES DON'T SEEM TO HAVE ANY COMMON SENSE!
