Bottom line just because nut cases exist in the world doesn't mean I don't have the right to protect myself and my family.
Excellent point
Let me tell you a story about a non militia situation.
I lived in NYC during hurricane Sandy. A friend of mine, lifelong new yorker, lived on a affluent area of the south shore of Long Island. Early 40's, never owned a gun in his life, never thought about owning one. After hurricane sandy his whole community became completely cut off, declared a disaster area and left to its own. The were no civil anything there, no police, no fire, nothing, but the people were still there, families in their homes. Rules change when there is no police, he told me he never felt so vulnerable in his life. Those intent on harming and stealing entered other peoples houses at will. Here is a grown man, with a wife and two young children and no options for protection. From that day forward he realized the insurance value of owning a firearm, some of his neighbors had written on their houses that they were armed and not to try to break in. This was not an overnight thing by the way.
You see a gun can be like care insurance. Its something you hope you never need. But the time you might need it can be out of your control. In his situation it wasn't rising up against the government, the WAS NO GOVERNMENT. Gone overnight. An affluent relatively safe place turned into a lawless free for all in a very short amount of time. No police, no national guard. It happens.
