A careful and thorough examination of the 2nd Amendment suggest that it is very different from what many people think. In fact, rather than giving US citizens a free choice of all and any Gun they may like, the 2nd Amendment can be used to prevent the most dangerous people from having easy access to guns. The DC vs Heller (2008) case, gave Dick Heller the right to have a gun in his home for protection. However, Dick Heller was a police officer and, therefore, qualified as a member of a ''Well Regulated Militia.'' Other gun owners may not be qualified to have a gun for personal protection as was Dick Heller. The present book suggests how gun owners can be qualified to have a gun for personal protection while also limiting dangerous people from easy access to guns.
