The possibility that the D.C. dispute could jeopardize a range of federal firearms laws — including those banning individuals from owning machine guns and those establishing rules for transporting weapons — has led the Bush administration to take a step back from its strong support of gun rights.
Emphasis mine. Machine guns are not banned, just regulated by the NFA. To a greater degree they are regulated by price thanks to the Firearm Owners Protection Act (FOPA). The second thing I found was:
The court did not directly address the scope of the Second Amendment. Yet its decision rested on the notion that the Second Amendment protects a collective right to firearms, not an individual right.
It didn't "rest on the notion." The Supreme Court didn't rule one way or the other in the Miller case, and it doesn't support either side of the debate. Miller didn't bother to show up for the case and neither did his attorney so the court made a ruling "in absence of any evidence."
No doubt Mr. Heller and Mr. Gura will show so lets hope the court gets it right this time.
