Mr. Medved is right. Nothing will stop these Mass Murders/Massacres 100%. That being said there is a way to take away the confidence of these Murderers. There is a way to take away the perception of easy targets. The one commonality in all Mass Murders/Massacres on U.S. soil over the last 50yrs, is that they all took Place in "Gun Free Zones". Take away the easy targets...take away the sense of confidence that the terrorists will be unopposed. Take away the perception that no one will shoot back and you take away the terrorists belief of an advantage.
Ban All Gun Free Zones!
God Bless America!
