Whether the ordinance was facially invalid under the First Amendment overbreadth doctrine because it burdened speech or association.
Holding
No. The Court concluded that the ordinance did not substantially reach First Amendment-protected activity and therefore did not rest its decision on overbreadth.
Reasoning
The ordinance did not prohibit speech, and its definition of loitering excluded conduct with an apparent purpose. As a result, it did not by its terms reach demonstrations or other assemblies that were apparently intended to communicate a message.
The Court also concluded that the ordinance’s effect on ordinary social contact between gang members and others did not impair the limited First Amendment right of association recognized in the Court’s precedents. Its invalidity instead arose from due-process vagueness.
