At present, we’ve reached the point where the Second Amendment can be characterized as ordinary constitutional law. That is, it now protects a right that attaches to individuals, and that those individuals can enforce in federal court.

Of course “ordinary constitutional law” doesn’t mean that everything is settled — in fact, an area in which all the legal questions were settled once and for all would be more like extraordinary constitutional law. But it does mean that questions relating to gun ownership, gun carrying, and the like are now dealt with in the same way that federal courts deal with other questions of constitutional rights…

This is a state of affairs that seemed almost inconceivable a mere two decades ago, and therein lies a reminder: It often seems as if the deck is stacked, and change is inconceivable. Twenty years ago, the prospect of this kind of expansion in constitutional freedom seemed very dim. But in America, change, when it comes, can be sudden and dramatic — even when, as here, the general current of punditry and political opinion seems set in stone. Keep that in mind, as you contemplate other political issues.
