You want Obama to have the power to declare all gun owners to be "enemy combatants" ???/QUOTE]
Until I read the verdict, I'm siding with SCOTUS on this for exactly such a reason. War has not been declared, and the festivities in question were prompted by a mere dozen maniacs 6+ years ago; this does not IMHO warrant separating me from loss of my rights by absence of a mere two words. Methinks those involved were better dealt with where found.
Why do people keep dwelling on "self-defense in the home"?
Because that's the right place to start the discussion from, considering how badly the right has been damaged. Under current circumstances, "a Glock in a home in DC" is much easier to demand rights to initially than "an MP5 on the street in Chicago" ... but having reached the first, the second becomes much easier: simple personal ownership of an otherwise common tool in a federal enclave lacks the obfuscations of state jurisdiction, city jurisdiction, public carry, NFA, importation, and other issues that have repeatedly derailed other attempts to get the core right recognized & protected.
even most gun owners agree ... .223 AR-15's are not ideal home defense weapons
I don't care much what polls say. Those who understand the tools & scenarios are rapidly turning toward exactly that tool for that purpose. The voting populace, and the powers that be, being far from acknowledged experts on the subject (or minor deities) are not in a position to trump a citizen's choice of tools for a given scenario ... hence the reason why the 2ndA is written with the unlimited term "arms" and the imperative "shall not be infringed". Just because a tool has not yet been broadly adopted does not mean it won't be, and that those who have to use what they choose might be the best in making that choice.
