Hahvahd Eggheads Versus SOPA

Harvard Researchers Explain That SOPA Supporters Are Misusing Their Research To Support SOPA.  Read it from Harvard Law School with this at the end:

... our decade-long study of Internet filtering and circumvention has documented the many problems associated with Internet filtering, not its overall effectiveness.  DNS filtering is by necessity either overbroad or underbroad; it either blocks too much or too little.  Content on the Internet changes its place and nature rapidly, and DNS filtering is ineffective when it comes to keeping up with it.  Worse, especially from a First Amendment perspective, DNS filtering ends up blocking access to enormous amounts of perfectly lawful information.  We strongly resist the claim that our research, and that of our collaborators, makes the case in favor of DNS-based Internet filtering.
