Thanks for this. I admit I wasn't aware of it. I would still like to see how the courts would handle a similar issue to at least get an idea of how the courts expand and or limit Heller in future rulings.
And I agree with Glenn about the mob mentality in Washington. A rash of shooting could very well put enough pressure on members of congress that they feel such a ban would be necessary no matter the failure of prior attempts with similiar legislation.
Hopefully Heller has set the legal groundwork for the courts to strike down such bans.
