"What is gained by not releasing that information?" Must be fear-based. First they threaten to open a can of worms, then something causes them to pull back. This time, just after meeting with an attorney. (Correct me if I'm wrong about the attorney part.)
I'm not sure that they are afraid of much, especially in trying to find out what happened. Can't see as how coming forth with anything, IF they have anything, can hurt a case that is already evaporating like a rain drop on a hot sidewalk in Aruba.
