There is an important post by Faisal of the Spittoon up at Comment is Free:
It is now clear US army major Nidal Hasan had a series of connections to the Islamist cleric, Anwar al-Aulaqi. For those of us who have studied, with increasing concern, the extreme teachings of this cleric, this tragedy is the inevitable consequence of unchecked Islamist radicalisation. This situation has been made all the more distressing by the apparent lack of concern shown by the US intelligence and military authorities in taking Aulaqi’s influence seriously. I fear that, in the United Kingdom, the authorities are similarly turning a blind eye to Aulaqi’s followers.
