16Am Jur 2d., Sec. 256:
“The general rule is that a unconstitutional statute, whether Federal or State, though having the form and name of law as in reality no law, but is wholly void and ineffective for any purpose since unconstitutionality dates from the enactment and not merrily from the date of the decision so braining it. An unconstitutional law in legal contemplation is as inoperative as if it never had been passed. Such a statute lives a question that is purports to settle just as it would be had the statute not ever been enacted. No repeal of an enactment is necessary, since an unconstitutional law is void. The general principles follows that it imposes no duty, converse no rights, creates no office, bestows no power of authority on anyone, affords no protection and justifies no acts performed under it.

They already had 4 years to come into compliance with the previous Supreme Court Ruling, So why should then now be allowed another 180 days to screw up the Constitutional Rights of the DC residents and visitors again?

All they have to do is copy and enact “gun carry licensing mechanism” from one of several states that abide by the Constitution.

Being as that registration process is somewhat akin to becoming a Jedi Master (As documented by Emily below), that would seem to mean that a DC resident is going to have exactly the same giant ball of paperwork to push eternally up the hill as before, while an out of state resident might just possibly be able to drive through the district with an empty shell casing in their car without fear of being thrown in jail for ten years.

That would be the Dick Gregory rumored to be under psychiatric evaluation by his employer?

The irony. Delicious.
