I sure am glad we have the Circuit Court of Appeals for the District of Columbia there to explain plain english for us. I won't be completely satisfied, however, until the Supreme Court explains to everybody that the word 'bear' means carry, not own. Could you imagine Thomas Jefferson paying money to the government for the right to conceal his weapon on his person?
I am unaware of any evidence from the 18th Century that there was ever any claimed right for people to carry concealed armaments. However, in today's world, the right to carry arms, combined with the fact that open carry will usually result in harassment, would imply a right to carry concealed.
Very good point - the thought that you would have to file papers an pay to carry a weapon would cause old Tom to turn in his grave.
