Supreme Court Rules That Individuals Have Gun Rights

The conservatives at SCOTUS have overturned Washington D.C.'s ban on handguns. But they do recognize that guns are not appropriate in some places ... such as their own offices. Your office (and school and church, etc.) is another matter, it seems. I also wonder what is a 'firearm'. Are RPGs allowed? Bazookas? It would seem so. From Supreme Court Rules That Individuals Have Gun Rights:

Scalia said nothing in Thursday's ruling should "cast doubt on long-standing prohibitions on the possession of firearms by felons or the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings."
