This news from the trial of Zacarias Moussaoui — An FBI agent testified Monday the government ignored warnings that could possibly have prevented the 9/11 attacks. Greg Samit, who arrested Moussaoui in August 2001, said he spent four weeks trying to convince his superiors Moussaoui posed a security risk. According to Samit, the warnings were made at least seventy times, and FBI officials were even told of a specific threat of a plane attack on the World Trade Center. But Samit said his efforts were stonewalled. Samit blamed his superiors’ “obstructionism, criminal negligence and careerism” for blocking “a serious opportunity to stop the 9/11 attacks.”
