Andrew C. McCarthy believed that sections (deals with Pen Register and Trap and Trace Authority under FISA) and (expanded what records could be accessed under FISA) should be retained. He argues that the Federal Rules of Criminal Procedure, Rule 17(c), authorizes the compulsory production of "any books, papers, documents, data, or other objects" to criminal investigators by mere subpoena, and so section 215 merely brought FISA into line with current criminal law. He also states that the records included in section 215 are records held by third parties, and therefore are exempt from a citizen's reasonable expectations of privacy. In light of this, McCarthy believes that there are three main reasons why the access to library records is not a problem: firstly he believes that the government has always had the authority to compel the reading of records by subpoena and there has been "no empirical indication of systematic prying into private choices – else we'd surely have heard from the robustly organized librarians"; secondly he believes that in the current information age that there is just too much information for inappropriate access to such records; and thirdly he believes that an "a priori" ban on the investigative access to the reading of records would be both unprecedented and wrong. He points out that "literature evidence was a staple of terrorism prosecutions throughout the 1990s" and that the reading of records has already led to convictions of terrorists.
