Where did this fruitcake get off deciding that the Bill of Rights does not apply within the District of Columbia. The whole point of the US Constitution is to constrain the powers of government. Is she suggesting that the District of Columbia should become a Forbidden City, where only the Emperor and his lackeys may enter and all other tremble with fear as they approach the walls and gates? This might yet be the nuttiest thing that a judge has yet written.
The brief in the first place is an excellent review of origin meaning and application of the 2nd amendment which everyone should read. Second, all it requests is that the Supreme Court clarify the standard of review relevant to this case and remand back to the lower courts for rehearing under the rules established by the Supreme Court. This is neither unusual nor unreasonable.
