@InfraBlue,
Machine guns were not extensively used in murderous crimes to begin with.
Had they been, that alone would not have been enough to provide a compelling government interest in restricting access to them.
Access to machine guns was restricted because they are significantly more lethal than normal weapons.
Neither are AR-15 rifles used extensively used in murderous crimes today.
Merely being used extensively in murderous crimes is not in itself enough to provide a compelling government interest in restricting access to something.
That is why it is unconstitutional to restrict access to handguns despite the fact that they were used far more extensively in murderous crimes than machine guns were.
That's why it is unconstitutional to restrict access to handguns despite the fact that they are used far more extensively in murderous crimes than AR-15 rifles are.
Providing an example of something that is used far more extensively in murderous crimes than machine guns were, that it is unconstitutional to restrict access to despite that more-extensive use, undermines your claim that extensive use alone would provide a compelling government interest in restricting access to machine guns.
