 Justice Samuel Alito wrote a separate concurring opinion , in which he was joined by Justice Anthony Kennedy and Justice Sonia Sotomayor . He agreed that content @-@ based regulations present the same dangers as viewpoint @-@ based regulations because content @-@ based regulations " may interfere with democratic self @-@ government and the search for truth " . He also agreed that the town 's ordinance was " replete with content @-@ based distinctions " that were subject to strict scrutiny . However , Justice Alito wrote separately to emphasize that the Court 's opinion would not " prevent cities from regulating signs in a way that fully protects public safety and serves legitimate esthetic objectives " . To support his argument , Justice Alito provided a list of examples of content @-@ neutral sign regulations , including : regulations that target the size of signs , regulations that target the locations at which signs may be placed , regulations distinguishing between lighted and <unk> signs , regulations that distinguish between the placement of signs on public and private property , rules that restrict the total number of signs " per mile of roadway " , and rules that distinguish between freestanding signs and signs that are attached to buildings .
