A grad student from Cal got arrested taking photographs and otherwise doing journalism in Egypt. As the authorities are hauling him away, he uses his cell phone to post a one-word message on his Twitter blog: “Arrested.” Tipped off to his predicament, his friends, both in Egypt and in the States, rally support for him and he is quickly released. His follow-up message: “Freed.” Now he wants to help out his translator, who was arrested along with him. I hope he does.
