CSI in Real

　　Past few weeks I introduced you the American series CSI: Crime Scene Investigation, it is about investigating murder cases. How about the real crime scene investigation? Is it just like what acted in the drama?

 　　I found a video on the Internet, it was focused on the investigation in the real life. According to the video, the real crime scene investigation is not as fast path as what preformed in the series, sometimes it took several months for solving a case. The technique used to examine the clues also takes a lot of time to operate. The largest difference between the investigation in the series and in the real life is that it is not always that easy to find so many evident. Sometimes it just nothing can be found in the crime scene. It's really a time-taking work!

　　When I was searching for the information, I accidentally saw this video, it's about crime scene cleaning. I think it's really an important work, and also take a lots effort. Let’s take a look at it!
