According to one reader/reviewer, “As a former police reserve officer, I spent years requesting CSI with little understanding of just what they do. This book goes well beyond lifting fingerprints and other routine tasks that police officers are typically limited to. I now have a better awareness of the capabilities of CSI and considerations about how to protect a scene and how CSI can be used to investigate certain crimes. I also have a greater appreciation for CSI personnel and the difficult job they have. I liked the book and believe it would be helpful to anyone in law enforcement.”
