Read my sister La Shawn Barber's characteristically no-nonsense, bottom-line, Biblical thoughts about the rioting and looting. The problem is that most of the people in the disaster area probably do not have, and many have never even heard, La Shawn's Biblical perspective. And we are seeing in the news every day the truth of Proverbs 29:18 -- "Where there is no prophetic vision [i.e. the Word of God, known and heeded] the people cast off restraint, but blessed is he [i.e. the people, the nation] who keeps the law."
Hugh Hewitt keeps up on some of the best blogging on the hurricane; visit him frequently. He is part of the organized blogging effort to encourage giving for this disaster. I am particularly struck by the truth Col. Austen Bay's words: "There's no America out there except America to respond to it. We've got to do it ourselves."
For our part, we will give through my wife's work, which will add their funds to employees' donations. LaShawn recommends the Salvation Army, Hugh recommends Feed the Children. Then there is Samaritan's Purse. Do pick one at least, and give.
