The 80 percent figure came from one of the intercepted al Qaeda communications. I will try to find it and post a link.

I do not think public affairs offices are set up to respond in a timely way to enemy media campaigns. The best analogy I can think of off hand is a groups of trial lawyers responding in real time to the other side in complex litigation situations. They have the sense of urgency to get their sides position out there and to tear down the assertions of the other side. If properly manged by a skilled attorney they can be devatatingly effective. This is not the same as lawyers giving legal advice on operational matters. It is about presenting a case in an understandable way that ordinary people can understand. Trial lawyers are very different from deal lawyers in terms of their OODA loops. They can't afford to let testimony bad for their case just hang out there without dealing with it while it is still fresh in the minds of the fact finders.
