I don't know if any of you guys heard of the musician Moby, but he was in New York when the atrocity occured. He has his own website and has been posting on his view of things on a daily basis. I found it interesting. Earlier entries are critical of security services, but he goes on to apologise, citing 'anger at the time'.
