From The Truth About Guns:

Of course powerful, wealthy, politically-connected elites are exceptions, routinely obtaining the rare and coveted unrestricted handgun carry licenses that are unavailable to the average citizen.
And criminals don’t obey handgun licensing rules or any other state or city law pertaining to firearms, so they don’t care how many laws the city enacts. This hasn’t changed and never will.
But it’s deeply troubling to believe New York City’s harsh, even despotic handgun licensing scheme continues to escape constitutional scrutiny, a point Halbrook makes at the outset of his article, when he states,

“‘Under New York law, it is a crime to possess a firearm’, held the U.S. Court of Appeals for the Second Circuit in U.S. vs. Sanchez-Villar (2004). This ruling was based on the state’s ban on the possession of an unlicensed handgun. This prohibition did not offend the Second Amendment, said this ruling, because ‘the right to possess a gun is clearly not a fundamental right.’ Later rulings by the U.S. Supreme Court—D.C v. Heller (2008) and McDonald v. Chicago (2010—begged to differ. . . . But the Second Circuit must not have gotten the memo. . . .”
