I think this is positive in two ways.
First, what AN said. Working together and improving communication. I think its easy for BS to take the righteous indignation thing way to far.
Second, you have suffered a trauma and a tragedy. What other benefit could possibly come from that other than learning. Pain, much more so than joy, is a teacher. Learn. You don't have to be thankful for the lesson, but learn it none the less.
Human. The rub is have have to watch those rascals like a hawk!
