What legal reasoning? Let's try common sense, first. Scalia needed twenty pages to try and convince the other justices to vote with him on Heller, he succeeded only to convince the other three conservatives.
The liberals were not going to be swayed by any argument no matter how long or short. They were unwaveringly on the side of upholding the DC statutes no matter how ridiculous their explanations sounded . . .
You are correct,
Heller was much too long. Scalia screwed the pooch with a textual analysis.
Heller should have been a five sentence opinion just quoting SCOTUS precedent.
"District of Columbia v. Heller, 554 U.S. 570 (2008), . . . was the first Supreme Court case to decide whether the Second Amendment protects an individual right to keep and bear arms for self-defense"
District of Columbia v. Heller - Wikipedia the free encyclopedia
Sigh . . . Wikipedia scholarship sure is lacking.
What you highlight is wrong.
In the very first RKBA case heard by the the Court it recognized the right to keep and bear arms of two Freemen in 1873 Louisiana for the "lawful purpose" of self-defense from the KKK outside their home.
Reading from and quoting the indictment of the men who disarmed, kidnapped and lynched the two former slaves, the Court said:
"The second and tenth counts are equally defective. The right there specified is that of "bearing arms for a lawful purpose." This is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The second amendment declares that it shall not be infringed, but this, as has been seen, means no more than that it shall not be infringed by Congress."
Ten years later in
Presser, the Court revisited
Cruikshank and quoted it but substituted the
Cruikshank case specific language with the simple and recognizable wording of the 2nd Amendment (internal quotation marks removed):
"the right of the people to keep and bear arms is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The Second Amendment declares that it shall not be infringed, but this, as has been seen, means no more than that it shall not be infringed by Congress."
In
Heller, the Court re-re-re-affirmed the principle of retained, pre-existing rights and revisited
Cruikshank:
"it has always been widely understood that the Second Amendment , like the First and Fourth Amendments, codified a pre-existing right. The very text of the Second Amendment implicitly recognizes the pre-existence of the right and declares only that it “shall not be infringed.” As we said in United States v. Cruikshank, 92 U. S. 542, 553 (1876) , “[t]his is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The Second amendment declares that it shall not be infringed … .”"
Your "common sense" is legal nonsense.
Please explain the legal reasoning you think will force the Court to ignore its earlier ruling on the pre-existing nature of the right to arms and to find that the right is actually entirely dependent upon a collectivist interpretation of words that the Court has said repeatedly the right in no manner depends upon.
Yeah, you're just a fountain of common sense . . .
