So he's right.
See Senator Feingold's critical commentary on the so called reform on Truthout.org:
http://www.truthout.org/docs_2006/021506R.shtml Statement of US Senator Russ Feingold as prepared for delivery from the Senate floor, February 15, 2006.
<...NSLs can only be used to obtain certain categories of business records, while Section 215 orders can be used to obtain "any tangible thing." But even the categories reachable by an NSL are quite broad. NSLs can be used to obtain three types of business records: subscriber and transactional information related to Internet and phone usage; credit reports; and financial records, a category that has been expanded to include records from all kinds of everyday businesses like jewelers, car dealers, travel agents and even casinos.
Just as with Section 215, the Patriot Act expanded the NSL authorities to allow the government to use them to obtain records of people who are not suspected of being, or even of being connected to, terrorists or spies. The government need only certify that the documents are either sought for or relevant to an authorized intelligence investigation, a far-reaching standard that could be used to obtain all kinds of records about innocent Americans. And just as with Section 215, the recipient is subject to an automatic, permanent gag rule...>
<...One of the most fundamental protections in the Bill of Rights is the Fourth Amendment's guarantee that all citizens have the right to "be secure in their persons, houses, papers, and effects" against "unreasonable searches and seizures." The idea that the government cannot enter our homes improperly is a bedrock principle for Americans, and rightly so. The Fourth Amendment has a rich history and includes in its ambit some very important requirements for searches. One is the requirement that a search be conducted pursuant to a warrant. The Constitution specifically requires that a warrant for a search be issued only where there is probable cause and that the warrant specifically describe the place to be searched and the persons or things to be seized.
Why does the Constitution require that particular description? Well, for one thing, that description becomes a limit on what can be searched or what can be seized. If the magistrate approves a warrant to search someone's home and the police show up at the person's business, that search is not valid. If the warrant authorizes a search at a particular address, and the police take it next door, they have no right to enter that house. But of course, there is no opportunity to point out that the warrant is inadequate unless that warrant is handed to someone at the premises. If there is no one present to receive the warrant, and the search must be carried out immediately, most warrants require that they be left behind at the premises that were searched. Notice of the search is part of the standard Fourth Amendment protection. It's what gives meaning, or maybe we should say "teeth," to the Constitution's requirement of a warrant and a particular description of the place to be searched and the persons or items to be seized...>
(comment: national security letters are the meaningless Orwellian substitute for warrants our elected representatives are using to eviscerate the First and Fourth Amendments.)
