Via Reason: 

Ten years ago this week, the Supreme Court for the first time explicitly recognized that the Second Amendment protects an individual right to armed self-defense. Since then the Court has revisited the subject only twice, while it has heard about 45 cases involving the Fourth Amendment and about 60 involving the First.

That stark disparity reflects a failure noted by critics on and off the Court. After waiting more than two centuries to acknowledge that the Second Amendment imposes limits on legislation, the Court has passed up dozens of opportunities to clarify the extent of those limits, leaving the task to lower courts that are often hostile to gun rights...

Thomas has repeatedly complained about his colleagues' neglect of the right to arms, calling it "this Court's constitutional orphan." Antonin Scalia, who wrote the majority opinion in Heller and died in 2016, joined Thomas's dissent from the decision not to scrutinize the Highland Park "assault weapon" ban, and Scalia's replacement, Neil Gorsuch, agreed with Thomas that the Court should have reviewed California's "near-total prohibition of public carry."

Three other current justices joined the majority in Heller. Since it takes four votes for the Court to accept a case, at least two of them seem reluctant to say anything further about the Second Amendment. Judging from Samuel Alito's concurring opinion in the stun gun case, which faulted his colleagues for a "grudging" decision that stopped short of overturning the ban, the two holdouts are probably John Roberts and Anthony Kennedy.
