In Boos v. Barry, 485 U.S. at 320-21, the Court also looked to City of Renton. In Boos, the United States argued that an ordinance restricting speech critical of foreign governments near their embassies was justified based on an international law obligation to shield diplomats from speech that offends their dignity. The Court, in declaring that part of the law unconstitutional, distinguished City of Renton because the ordinance restricting speech near embassies was: justified only by reference to the content of the speech. Respondents and the United States do not point to the "secondary effects" of picket signs in front of embassies. They do not point to congestion, to interference with ingress or egress, to visual clutter, or to the need to protect the security of embassies.

This justification focuses only on the content of the speech and the direct impact that speech has on its listeners. Id.
