Where are the lawyers?

Surely the pernicious damages lawyers should be circling the Hurricane Katrina victims by now? I would have thought they would have been first on the scene. Sueing is part of the American way of life. When my good friend, Peter, lost his parents in a Pan Am crash over Baton Rouge, he had to be physically protected from the avalanche of compensation lawyers which descended upon the victims' families. So why aren't they swarming now? There must be somebody they can sue on behalf of those poor people whose babies which died for lack of fluids, grannies who died similarly from the ineptitudes of care in those godforsaken refuges or those hospital patients who were left to drown or die from neglect. FEMA comes to mind. Homeland Security, too. But of course those bodies would be constitutionally free of liability. Which is the only explanation one can find for the lack of a legal feeding frenzy.
