Je Suis Facebook? Mark Zuckerberg's Post Raises Free Speech Questions

"Implementing a pro-speech policy internationally has its own challenges because — even in the West — there is not a unified legal approach to protecting free speech," Morgan Weiland, a graduate fellow at the Center for Internet and Society at Stanford Law School, told NBC News.

Of course, monitoring posts for all of these factors is a Herculean task. The fact that Facebook is approaching it with a sense of idealism is encouraging to Neil Richards, a law professor at Washington University in St. Louis.

"I think what Zuckerberg is trying to say is that Facebook is committed to Western notions of freedom of speech," Richards told NBC News. "I think that is true and laudable."
