In Adderly v. Florida, 385 U.S. 9, 47, 87 S.Ct. 242, 247, 17 L.Ed.2d 149 (1966), the petitioners had assembled on the grounds of the county jail to protest peacefully the racial segregation at the jail. This kind of activity has generally been protected by the First Amendment. See, e. g., Edwards v. South Carolina, 372 U.S. 229, 83 S.Ct. 680, 9 L.Ed.2d 697 (1963); Cox v. Louisiana, 379 U.S. 536, 559, 85 S.Ct. 453, 466, 13 L.Ed.2d 471 (1965); Brown v. Louisiana, 383 U.S. 131, 86 S.Ct. 719, 15 L.Ed.2d 637 (1966). Nonetheless, the Court rejected the petitioners' argument that they had a constitutional right to stay on the property because they believed the area was particularly appropriate for the demonstration. 385 U.S. at 47, 87 S.Ct. at 247. Despite the fact that this assembly was nondisruptive and the fact that the grounds were not marked with "No Trespassing" signs, the Court ruled that the First Amendment did not preclude the state from controlling the use of its property for its own purposes and prohibiting the petitioners from speaking and assembling there. Id. at 47-48, 87 S.Ct. at 247.
