I want to know the answer to the following question:
What did Section 215 of the Patriot Act allow the FBI to search?
All the background I'm provided with is that "On 30 July 2003, the American Civil Liberties Union (ACLU) filed the first legal challenge against Section 215 of the Patriot Act, claiming that it allows the FBI to violate a citizen's First Amendment rights, Fourth Amendment rights, and right to due process, by granting the government the right to search a person's business, bookstore, and library records in a terrorist investigation, without disclosing to the individual that records were being searched.". Is that enough to answer the question?
Answer: yes
