This is beside the point. The point is that EVEN if the cross-communication had been done, this information is not actionable. It's not actionable by itself -- and even less so compared to the thousands of intercepted messages saying 'BLOOD WILL RUN IN THE STREETS OF WASHINGTON!' that they must get all the time.
I agree that the security agencies interoperate poorly or not at all. But the issue is whether the information, translated in a timely manner or not, would have changed anything. The answer seems to be 'no'.
