Want to know how often a neighbor or fellow citizen used a gun for defense purposes? Check out this interactive map by the Heritage Foundation. These are only the reported cases that seem only to get as far as the local media.
Often the media and gun-grabbing politicians would have you believe Greenwood Mall, which occurred in the middle of July, is a rarity as they strip away and outlaw your ability to defend yourself and your loved ones. However, as of this posting, I was able to find at least 6 defensive uses since the Greenwood Mall that you likely have not heard about unless they occurred in your local news market.
