Justice Kennedy, who authored the dissenting opinion in Colorado v. Hill in 2000—in which the majority of the Court upheld a Colorado buffer zone law—expressed during oral arguments his view that the Massachusetts buffer zone law as a one-sided attempt to restrict speech around abortion, rather than as an attempt to prevent violence or intimidation.   He and Justice Alito pushed Massachusetts Assistant Attorney General Miller on this point, asking how it could be that a clinic staff may speak to women within the buffer zone, but that protesters may not.   Miller responds that the clinic employee is “actually doing her job,” and that even the petitioners have not argued that there is any “viewpoint discrimination actually happening in the buffer zone.”
