CEP Executive Director writes in the Hill: "Fort Hood shooter Nidal Hasan. Boston Marathon bombers Dzhokar and Tamerlan Tsarnaev. Underwear bomber Umar Farouk Abdulmutallab. Garland, Texas, gunman Elton Simpson. All of these terrorists were deeply influenced by the American-born al-Qaeda operative and propagandist Anwar al-Awlaki, who continued to radicalize and encourage indiscriminate killing long after his 2011 death, thanks to the easy accessibility of his sermons and lectures on YouTube and other Internet platforms. Last November, Google took the exemplary step of removing most Awlaki content from its video-sharing platform YouTube. While that action was commendable, much more work is waiting to be done. Sadly, Awlaki was just one in a sea of similar, radical voices. The tech giant must set an example for the rest of the industry by blocking not just Awlaki but other, noxious extremists from using all of its platforms and encouraging other tech companies to do the same."
