I guess I understand, it is a sensitive situation. Officials have to seize the opportunity they have to not only prevent future attacks but also gain all of the information they can from the suspect. If details of the investigation are made public it kind of hinders the effort of tracking down the source. Speculation is fine which is all we can do for the time being but that attempt was not thought up by an amateur, there is a bigger picture and I'd assume they are going after that bigger picture.
