Handguns are also great protection against robbers and murderers. If you have one, just make sure you know how to use it. A handgun in untrained hands is not a good thing.

Justice Scalia was quite thorough on the historical, analagous and legal analysis. The individual is the cornerstone to a civil guard, and the government - if it has total control over all facets of "arms" - becomes dictatorial. There have been many examples of this in other nations before and after the writing of the Constitution.
