At a crime scene, patrol officers, investigators, and others need to do a lot of things simultaneously. They must create and maintain an inner and outer perimeter, ensuring that access is only given to those who warrant it. They must begin a crime scene log and maintain it all the way through. They must preserve evidence, and make note of how evidence may have been affected by responding EMTs and/or firefighters. In this podcast episode, Jim and Doug discuss the best practices for ensuring that the scene is processed thoroughly and properly.
