I only want to comment on your saying some people say "the Second Amendment gives us that right". They certainly do say that, and it is untrue. The Bill of Rights and the Constitution do not GIVE us any rights. In the case of the Second Amendment, or as I prefer to refer to it as, Article Two of the Bill of Rights, it states these rights (pre-existing) shall not be infringed. We do not get these rights from the Constitution. The Constitution protects them.
That may, to some people, be a minor point. It certainly wasn't to the Founding Fathers.
