On the whole, librarians rock.

Mr. Cohen said in an interview on Monday that he and Ms. Glick-Weil demanded the warrant because the FBI agents did not indicate that anyone at Brandeis faced a "clear and present danger." If there had been such a danger, Mr. Cohen added, agents probably would have seized the computers without even asking for them.

"We were able to both protect public safety and also protect the rights of people, the sense of privacy of many, many innocent users of the computers," he said. "Had we given them the computers, they would have gotten to see e-mails from ordinary citizens doing ordinary things and would not have preserved privacy."

FBI Agents Back Down When Librarian Refuses to Let Them Seize 30 Computers Without a Warrant
By ANDREA L. FOSTER

An e-mail threat that prompted the evacuation of more than a dozen Brandeis University buildings on January 18 led to an unusual standoff in a public library in Newton, Mass., a few miles from the Brandeis campus.

Federal Bureau of Investigation agents tried to seize 30 of the library's computers without a warrant, saying someone had used the library's Internet connection to send the threat to Brandeis. But the library director, Kathy Glick-Weil, told the agents they could not take the machines unless they got a warrant first. Newton's mayor, David Cohen, backed Ms. Glick-Weil up.

After a brief standoff, FBI officials relented and sought a warrant from a judge. Meanwhile, Ms. Glick-Weil allowed an FBI computer-forensics examiner to work with information-technology specialists at the library to narrow down which computers might have been used to send the threatening message. They determined that three computers were implicated in the alleged crime.

Late that evening, the FBI received a warrant to cart away the three computers. According to Mayor Cohen, the warrant allows the FBI to view only the threatening e-mail message and the messages sent immediately before and after that message.
