Until we are told who was making 'an old-fashioned bank run,' we won't see the coordination. First was Shummer orchestrating a bank run, then this. What happened next is demonstrative of coordination.
Except there is an itty-bitty problem - there was a legitimate triggering mechanism. You have to apply Occam's razor here - an electronic panicked bank run in response to bad news is the simplest explanation. And you also have to demonstrate how a few individuals could control $500 billion in money market funds to be able to coordinate such a conspiracy.
