NO, it is NOT. Common decency and civility is what is expected from civilized people; the problem is that very few of the Superdome and Convention Center folks were civilized. What happened to the thousands of people that stood around and watched while the rapes were committed? Don't they have an obligation to help the victims?
The communists of AI assume that the relief organizations are REQUIRED to "police" their clients. Sorry, that is what the police are for. The aid groups have enough on their plate providing food, clothing, and shelter.
Sorry, but if "common decency and civility" were really an obligation, millions of US citizens would be in jail for that violation alone.
It is an obligation of civilized society, not a legal imposition. Many people, in stories I have read, displayed those traits at the Superdome and protected many women and children. Unfortunately, not enough did so.
