When U.S. officials asked the news media not to take pictures of those killed by Hurricane Katrina and its aftermath, they were censoring a key part of the disaster story, free-speech watchdogs said yesterday. The move by the Federal Emergency Management Agency is in line with the Bush administration's ban on images of flag-draped U.S. military coffins returning from the Iraq war, media monitors charged in separate telephone interviews. On Tuesday, FEMA refused to take reporters and photographers along on boats seeking victims in flooded areas, saying they would take up valuable space needed in the recovery effort and asked them not to take pictures of the dead. A FEMA spokeswoman wrote: "The recovery of victims is being treated with dignity and the utmost respect and we have requested that no photographs of the deceased be made by the media." FEMA's policy of excluding media from recovery expeditions in New Orleans is "an invitation to chaos," said Tom Rosenstiel, director of the Project for Excellence in Journalism, a part of Columbia University's journalism school.
