An independent review board concluded in its final report on Thursday that a controversial FBI electronic wiretap system was an effective law-enforcement tool, drawing fire from critics who said it was too invasive. In its final report to the U.S. Justice Department, a group of researchers at the Illinois Institute of Technology (IIT) added recommendations that the Justice Department should maintain tight central control of the e-mail monitoring system, dubbed "Carnivore." They also recommended that all comprehensive searches require Justice Department approval and that Carnivore be modified to document all of its activities to prevent abuse.

But much of the rest of the report remained unchanged from a draft version released last month, prompting criticism from the American Civil Liberties Union and House Majority Leader Dick Armey.
