The right, as written, includes the phrase "A well regulated Militia". This is the only right that includes the word "regulated". Personally, I would be in favor of a highly distributed form of regulation, similar to the "jury of your peers" system: to own a gun, you must join a militia, and it's up to that militia to determine if you're the type of person to randomly murder children or not. (This is similar to the idea I proposed after 9/11 that passengers be required to socially mingle with each other, and then (privately) share concerns with the airline or TSA. That is, the people with the most to lose are the best defense against these kinds of threats).
