Perhaps of greater interest is Justice Alito's concurrence, which reminds us that, even under an originalist view, modern technology is not outside the reach of our centuries-old constitution:
Electronic stun guns are no more exempt from the Second Amendment’s protections, simply because they were unknown to the First Congress, than electronic communications are exempt from the First Amendment, or electronic imaging devices are exempt from the Fourth Amendment . . . . As Heller aptly put it: "We do not interpret constitutional rights that way."Is this the beginning of the end of originalism? Talk amongst yourselves.
