Re: Forensic Views
There is also the "Howdunit" series of books. They are for mystery writing but they give a good insight into everything from crime scene investigation, poisons, and even how a police department is setup.
There are quite a few books in the series, I have about 14. So, if you need to know just what is in a patrol car or what a body looks like after being poisned these will help both you and your players.
