Legal experts from the right and the left agree that the 2nd amendment doesn't guarantee the the right to a gun let any weapon you want.
The Supreme Court has ruled that your right to own a firearm is only protected as long as it "has some reasonable relationship to the preservation or efficiency of a well regulated militia" (US vs Miller)
"A well regulated Militia, being necessary to the
security of a free State, the right of the people to keep and bear Arms, shall not be infringed." (Second Amendment)
Warren Burger, a former Supreme Court Justice, comments on how the true meaning of the second amendment has been distorted, "The Second Amendment has been the subject of one of the greatest pieces of fraud, I repeat the word, 'fraud', on the American public. The distortion of the intent of the framers of the Bill of Rights by the gun lobby is glaring, as they focus their argument on the last half of the amendment, while ignoring the first half, on which it was based."
Here's the ACLU take
Gun Control
"Why doesn't the ACLU support an individual's
unlimited right to keep and bear arms?"
BACKGROUND
The ACLU has often been criticized for "ignoring the Second Amendment" and refusing to fight for the individual's right to own a gun or other weapons. This issue, however, has not been ignored by the ACLU. The national board has in fact debated and discussed the civil liberties aspects of the Second Amendment many times.
We believe that the constitutional right to bear arms is primarily a collective one, intended mainly to protect the right of the states to maintain militias to assure their own freedom and security against the central government. In today's world, that idea is somewhat anachronistic and in any case would require weapons much more powerful than handguns or hunting rifles. The ACLU therefore believes that the Second Amendment does not confer an unlimited right upon individuals to own guns or other weapons nor does it prohibit reasonable regulation of gun ownership, such as licensing and registration.
