It seems that the OSU shooter was a fan of Al-Awlaki. I wrote before that Al-Awlaki's rhetoric is substantially different (and more dangerous) than the rhetoric of all Muslim clerics (including those who are quasi Westernized in Western countries). Al-Awlaki's style of preaching and agitation is much more likely to appeal to disaffected Muslims living in the West, and also to Westernized Muslims in Muslim countries. I don't think that we have heard the last of this dead man.
