British security sources tell NBC News that two of the five suspects in custody in connection with three recent terror incidents in Scotland and London are medical doctors and one may have assembled the bombs. Authorities also said they believe that most, if not all, of the suspects come from Middle Eastern countries, including one from Iraq.Unless I've missed something, this is the first time an Iraqi has been suspected of terrorism in the West since the invasion. What's his background? Did he lose family or relatives in the violence there? Did British participation in the occupation motivate him? It will be interesting to find out more, unless the authorities make it easy for everyone and put this in the self-explanatory file marked "Al Qaeda."
