On the evening of March 1, 2011, Arid Uka, an Albanian Muslim living in Germany, was online looking at YouTube videos. Like many before him, he watched a jihadist video begrudging the gruesome rape of a Muslim woman by U.S. soldiers—a clip edited and posted on YouTube for jihadi propaganda purposes. Within hours of watching the video, Uka boarded a bus at Frankfurt Airport where he killed two U.S. servicemen and wounded two others with a handgun.
