Remember the parable about the wheat and the cockle. The Lord is letting those who bear grow fruit to grow among the "weeds," which will also grow until the last day. Don't let it prevent you from helping those less fortunate. For every one looter, there are probably 5 people who aren't looting.
I remember in May of 95, I was taking a few science courses at Univ of NO, and we got hit by a similar flood. I was up to my knees in water walking back to my apt. No looting or riots. The reason the blacks (yes, the blacks, Dems, Socialists, anarchists, whatever) are doing this is bc of NO PENALTIES.
And Im thinking most of them will die anyway of disease (cholera, etc). If they didn't die of looting, they'd die of drug overdose, robbery shootings, drive-by shootings, etc.
In a word, they have it coming one way or another.
