I don't agree with what Alexander is implying. I think it's reasonable that there be a firewall around some assets.
That's not to say that I agree with Rosen's approach.
Seems like a conflict that Rhodes appointed Rosen, and now Rosen is securing the art. I would suspect that Rhodes has instructed Rosen to do what needed to be done so that Rhodes can put his stamp on the bankruptcy without looting the DIA.
