On 1/5/2009, NPR had a presentation on the DOJ Murals. The title of the article is "Murals Depict Law and Justice."
The NPR article (with a link to audio) is at: http://www.npr.org/templates/story/story.php?storyId=98783331
The slide show of pictures of the murals is at: http://www.npr.org/multimedia/2008/12/murals/index.html
