"It may be objected that if weapons that are most useful in military serviceM-16 rifles and the likemay be banned, then the Second Amendment right is completely detached from the prefatory clause."
"M-16 rifles and the like" does not have the same meaning as "rifles like the M-16." It means the same as "M-16 rifles, grenades, rocket launchers, squad machine guns, and the like." The Senator tried to get him to interpret what the common idiom "and the like" means, but he would have none of it. Good for him.
If Justice Scalia had meant "rifles like the M-16," he would have written that. He did not.
Feinstein completely misrepresented and misstated this quote. She had Scalia saying something he did not. Gorsuch apparently has not studied Heller. Or, he would have pointed out her twist.
