To educate and entertain my two young sons, I recently took them to our local science museum for an exhibit based on the popular television series, CSI. This exhibit was unlike others we have visited. When you enter, you are given an evidence card and watch a brief video from the star of the show. What struck me during this interview is a statement he made. Let me paraphrase it as I can't recall it as a quote. He said that dead victims are telling you what happened. The crime scene is telling you what happened. His advice? "Listen to the crime scene."
