I think you might have misread the article. David Reinhard is a conservative defending Scalia. It is the idiot E. J. Dionne who needs to remove his head from you-know-where.
I believe CDY is referring to my adding Reinhard’s name to the title following JUDGES.
Well, perhaps he should be reminded that the BoR doesn't "grant" anything; it merely enumerates pre-existing, natural rights.
As with religion, speech & assembly (1A), we have the right to self-defense, whether the threat comes from criminals, insurrection, enemies or tyrannical government, regardless of any written words.
The greatest irony, which seems to be missed by most, is that the 2A practically guaranteed its own affirmation. Even though it was 5-4, I believe a dissenting justice would have joined the majority if Kennedy had wavered. No one wants to play that level of brinkmanship to see if the People would really be pushed to CWII.
