SNIPPET: "Moeed Abdul Salam didn't descend into radical Islam for lack of other options. He grew up in a well-off Texas household, attended a pricey boarding school and graduated from one of the state's most respected universities." SNIPPET: "It is not clear to what extent Salam's family knew of his radicalism, but on his Facebook page the month before he died, he posted an image of Anwar al-Awalki, the American al-Qaida leader who was killed in a U.S. drone strike in Yemen, beside a burning American flag." SNIPPET: "The family, originally from Pakistan, immigrated to the U.S. decades ago."
