Al Jazeera reported: "He was asking about killing U.S. soldiers and officers," says al-Awlaki. "His question was, is it legitimate" under Islamic law.
More than a dozen e-mails followed, with Hasan asking al-Awlaki about martyrdom, about when jihad is permissible (about which al-Awlaki had written volumes), the death of innocent bystanders in attacks.
