As a native New Yorker I can tell you that City government will do anything in its power to obstruct RKBA. The only way that any significant headway will be made is for the court to eliminate entire classes of regulation, namely registration and licensing. Otherwise, it's all wasted breath. The City will obey the Supreme Court's ruling in letter but not in spirit. They'll give you the required permit...but only after a year of waiting and $2000. They'll let you register...but only after you make five separate trips to One Police Plaza with arcane paperwork at the most inconvenient hours imaginable. It'll be similar to black people trying to register to vote in some states in 1930. Sure, you have the right but good luck trying to exercise it in anything approaching a practicable matter.
