On April 10 2015, I had the opportunity to talk with GOP Presidential hopeful Dr. Ben Carson about guns and gun rights, and he told us that the Second Amendment keeps the government from dominating the people.
Carson talked about the importance of the Second Amendment:
The Second Amendment is incredibly important for a couple of reasons. Number one, our Founders felt that our nation, if ever invaded by outside forces, would be much stronger if the people could help repel those forces. Number two, and perhaps even more importantly, is if the government–our own government–ever became tyrannical, and wanted to dominate the people, the Second Amendment guarantees the people the means whereby to defend themselves.
