I refer you to my thread in world affairs, where Britain’s MI5 agency concluded that religious Muslims are less likely to be terrorists. Drugs/drinking/whoring and generally being less observant of Islam are part of the behaviours associated with some of those who go into violent paths.
Also, Ayman al-Zawahiri claimed that accusations that Al-Qaeda did not carry out 9/11 is a shia Iranian plot to discredit sunnis.
*Al-Zawahiri accused Hezbollah’s Al-Manar television of starting the rumour. “The purpose of this lie is clear, (to suggest) that there are no heroes among the Sunnis who can hurt America as no else did in history. Iranian media snapped up this lie and repeated it,” he said.
“Iran’s aim here is also clear, to cover up its involvement with America in invading the homes of Muslims in Afghanistan and Iraq,” he added. The authenticity of the audio could not be independently confirmed. But the voice sounded like past audiotapes from the terror leader, and the posting where it was found bore the logo of Al-Sahab, al-Qaeda’s official media arm. It was the second of two messages answering questions to al-Zawahiri that were posted to Islamic militant websites earlier this year.*
Now it could be that the tape was a fake, but in that case why hasn’t Al-Zawahiri made a statement saying this was false?
