NPR's Mark Roberts reports on the public release of a videotape that shows the library at Columbine High School shortly after the shooting rampage last April. While no bodies are shown, pools of blood are visible. The images were recorded by the Littleton Fire Department, which added a music soundtrack and used the video for training purposes. Some Columbine parents are very upset that the video has been made public. The State of Colorado says it is legally bound to release the tape.
