As late as 1964 Louisiana still refused access to African-Americans. This Supreme Court case tells you more:
BROWN v. LOUISIANA, 383 U.S. 131 (1966)
383 U.S. 131
BROWN ET AL. v. LOUISIANA.
CERTIORARI TO THE SUPREME COURT OF LOUISIANA.
No. 41.
Argued December 6, 1965.
Decided February 23, 1966.
For the purpose of peaceably protesting the denial of their constitutional right to equal treatment in a public facility, petitioners, five Negroes, entered the public room of a regional library operated on a segregated basis by the Louisiana parishes where they lived and another parish. No one was in the library room except petitioners and the library assistant. Petitioner Brown requested a book. The library assistant, after checking, advised that the library did not have the book but that she would request it from the State Library and that Brown would be notified upon its receipt. (The book was mailed to him at a later date, with instructions to mail it back or deliver it to the library’s “Blue” bookmobile, a facility reserved for Negroes only.) Thereafter the library assistant asked petitioners to leave. But, for the purpose of manifesting silent protest against the library’s segregation policy, Brown sat down and the others stood near him. There was no noise or boisterous talking. The branch librarian also asked petitioners to leave but they remained. In about 10 or 15 minutes from the time petitioners entered the library the sheriff and deputies arrived, having been forewarned, asked petitioners to leave, and were told that they would not. The sheriff then arrested them. Subsequently petitioners were convicted for violating the Louisiana breach of the peace statute, which makes it a crime “with intent to provoke a breach of the peace, or under circumstances such that a breach of the peace may be occasioned thereby” to crowd or congregate in a public building and fail or refuse to disperse or move on when ordered to do so by a law enforcement officer or other authorized person. Held: The decision below is reversed. Pp. 133-151.
