BU Today has an interview about the Wikileaks.org shut-down with Computer Science Department chair Azer Bestavros. His point–that “once the information makes it to the Internet, it’s impossible to take it back”–has profound implications about the ability of anyone, governmental or private, to restrict speech. It’s a point that Larry Lessig makes in his discussion of the Pentagon Papers case in Code 2.0 (Chapter 12, for those following the program): “Publishing requires a publisher, and a publisher can be punished by the state. But if the essence or facts of publication are punished elsewhere first, then the need for constitutional protection disappears. Once the piece is published, there is no further legal justification for suppressing it.” Professor Bestavros’s conclusion will be familiar to anyone who has taken my Internet law course or read Code 2.0: “Places like this bank should use much better technologies to protect their content.” In other words make if more difficult to leak sensitive information; rely on architecture, not law.
