A Manhattan Federal Court jury found Sulaiman Abu Ghaith, 48, Osama bin Laden’s son-in-law, guilty Wednesday  of providing support to terrorists and conspiring to kill Americans as an Al Qaeda spokesman around the time of the 9/11 attacks. Abu Ghaith spewed hateful speeches alongside Bin Laden in several Al Qaeda propaganda videos films, including one made outside a mountain cave in Afghanistan on Sept. 12, 2001, the day after the Twin Towers fell. It took the 12 jurors about a day to reach their verdict. The defendant faces a maximum sentence of life in prison.
