We should also be directing our prayers to the people of Haiti, whether at home or in shul.
Finally, just for those religious leaders who said the Haitians deserve what they got, I have a book for you to read. It is called the Bible. It talks about compassion for the widow, the orphan and the stranger.

People should be understanding and charitable to those who are in need. We in Michigan have been fortunate in reguards to disasters.
We Jews should be very proud of the response from Israel. They set the bar on quick turn time and organization.
