EFF has witnessed a growing number of calls in recent weeks for Twitter to ban certain accounts of alleged terrorists. In a December 14th article in the New York Times, anonymous U.S. officials claimed they “may have the legal authority to demand that Twitter close” a Twitter account associated with the militant Somali group Al-Shabaab. A week later, the Telegraph reported that Sen. Joe Lieberman contacted Twitter to remove two “propaganda” accounts allegedly run by the Taliban. More recently, an Israeli law firm threatened to sue Twitter if they did not remove accounts run by Hezbollah.

Lieberman clearly has absolutely no clue about freedom of speech.
