Use whatever epochal language you like, but this is a big one:
The Federal appeals court for the D.C. Circuit just struck down the District of Columbia's gun ban on Second Amendment grounds.
Watch this one--as the Volokh Report notes here, the political implications are wide-ranging.
BTW, it's not the first time a federal court has held in favor of the individual rights interpretation of the Second Amendment (it has started trending that way), but this is the first time legislation has been voided by a court on these grounds.
This is a story to follow, folks.
