This library has acted in accordance with ALA directives and statements. Here's evidence:
"When a public librarian in Delray Beach, Fla., recognized some of the suspected hijackers in the attacks on the World Trade Center and the Pentagon as men who had used the computers in her small library, she immediately called the police. That broke a Florida law that guarantees confidentiality to library patrons. It also violated a cardinal principle of librarians never to tell the police, in absence of a court order, about who uses their rooms and what books they check out. But almost no one thinks Ms. Hensman did the wrong thing." Except, of course, the ALA. "Judith Krug, director of the American Library Association's Office of Intellectual Freedom, said, 'I would have felt better if she had followed the Florida law.'"

The way I read this is that the ALA would have preferred the 911 terrorists library records were not made available to law enforcement until a law that should not apply to non-citizens trying to kill thousands of Americans was followed anyway.
