Why said anything about lawlessness? What *law* would stop a bunch of CDC experts from showing up at the hospital and saying to the admins, "Here we are, this is a very serious situation, and we've brought X and Y and Z resources to help. Let us help you please."
I *know* that if I'm a hospital admin, and there are these guys in my office offering that class of help, I'm not going to be saying "no".
So what laws would be broken, exactly? If the CDC offered that level of help (quite legally) and the hospital (also legally) told them to go take a hike, we'd know EXACTLY who to blame. Furthermore, the CDC would be on the spot in force able to cope with the screw up.
