Allow me to go Socratic method on you guys:
In one case a natural disaster struck, and its impact was arguably made worse by the failure of a dike built by the U.S. government. In the other case a private corporation with billions in profits had a major industrial accident. Should the U.S. government be equally responsible for responding in both cases? The U.S. government is trying to apply pressure on BP to fix the issue; who would it have pressured to fix Katrina's effects?
In one case people in a major city needed emergency relief and aid. In the other case, a well one mile deep in the middle of the Gulf of Mexico needs to be sealed. Is the U.S. government equally equipped to respond quickly in both cases?
I agree, if it leaks until December the results will be MUCH worse than Katrina.
