You will read things here that may be unpopular, may make you angry, and may save your life. Environmental crime scenes are especially dangerous to the world we live in. The proper processing and documentation of these scenes is important. This book is for you; not because I know so much, because I don't. It's because we know so little, are our own worst enemies, and because we forget so much. Sgt. Weissberg has served as a Police Officer, Administrative Officer, Crime Scene Investigator, Police Detective, and a Police Sergeant, and Acting Lieutenant.
