In November, 2001, al-Awlaki, while an iman in Virginia,
did an online chat with the Washington Post about Ramadan. He was asked about how the U.S. should have responded to the 9/11 attacks. Here's his answer:
Imam Anwar Al-Awlaki: The Taliban repeatedly said: show us the evidence and we will turn over whoever is guilty with the crime. The US should have given them the benefit of the doubt. Also our government could have dealt with the terrorist attacks as a crime against America rather than a war against America. So the guilty would be tried and only them would be punished rather than bombing an already destroyed country. I do not restrict myself to US media. I check out Aljazeerah and European media such as the BBC. I am seeing something that you are not seeing because of the one-sidedness of the US media. I see the carnage of Afghanistan. I see the innocent civilian deaths. That is why my opinion is different.
Keep in mind that I have no sympathy for whoever committed the crimes of Sep 11th. But that doesn't mean that I would approve the killing of my Muslim brothers and sisters in Afghanistan. Even though this is a dissenting view nowadays but as an American I do have the right to have a contrary opinion.
In 2002, a federal arrest warrant was issued for al-Awlaki in Denver for passport fraud and making a false statement to a federal official, but it was withdrawn before he was served with the warrant.
After 9/11, authorities learned that three of the hijackers visited al-Awlaki's California and Virginia mosques, but the FBI did not have enough evidence to arrest or detain him. In early 2002, he left the U.S. and started preaching on the Internet and applauding Palestinian suicide bombers.
It was while he was away that the U.S. Attorney's Office in Denver sought the arrest warrant. ABC News said it was based on the fact that al-Awlaki had attended CSU on a foreign-student visa, claiming he was born in Yemen, not in New Mexico, where he was actually born. Soon after he was briefly detained at JFK, he returned to Europe, and then Yemen.
