Inspired by pro-democracy uprisings across the Arab world, Libyan dissidents had planned a "day of rage" for Thursday, Feb. 17. On February 15, security forces arrested a prominent lawyer named Fathi Terbil, who had represented families of some of the 1,200 prisoners massacred by Libyan security forces at Abu Slim prison in 1996. Once released later that day, Terbil set up a webcam overlooking Benghazi's main square, where some of the families had been protesting. With help from exiled Libyans in Canada and around the world, the video spread rapidly on the Internet.
