This is a little old, so I'm surprised there wasn't a thread on it. The DC Federal Appellate Court threw out a longstanding DC handgun ban on 2nd Amendment grounds. This was decribed as the most sweeping interpretation of the 2nd Amendment ever.
Since this ruling conflicts with other Circuit Court rulings, there is also an excellent chance the Supreme Court will hear the case and if they do, similar laws across the country are in jeopardy. Gun opponents urged DC not to appeal the ruling to avoid giving the Supreme Court a chance, but DC has elected to appeal and they are awaiting word from the Supreme Court on whether they'll hear the case.
