The new Osama

One day in August 2001, Mr. Awlaki knocked at the door of Mr. Higgie, his neighbor, to say goodbye. He had moved the previous year to Virginia, becoming imam at the far bigger Dar al-Hijrah mosque, and he had returned to pick up a few things he had left behind.

As Mr. Higgie tells it, he told the imam to stop by if he was ever in the area — and got a strange response. “He said, ‘I don’t think you’ll be seeing me. I won’t be coming back to San Diego again. Later on you’ll find out why,’” Mr. Higgie said.

The next month, when Al Qaeda attacked New York and Washington, Mr. Higgie remembered the exchange and was shaken, convinced that his friendly neighbor had some advance warning of the Sept. 11 attacks…

One detective, whose name has been redacted, told the commission he believed Mr. Awlaki “was at the center of the 9/11 story.” An F.B.I. agent, also unidentified, said that “if anyone had knowledge of the plot, it would have been” the cleric, since “someone had to be in the U.S. and keep the hijackers spiritually focused.”
