Answer:
These behaviors are taught at the Police Academy and are basic common sense. Saying that as the Senior Officer you have to remind arriving Officers to stay out of the crime scene unless they absolutely have to pass thru the cordon. Officers are Not to Touch anything,... to move anything... to take unauthorized photographs of the crime scene . Obviously you always behave in a professional manner, save the gallows humor for later, It sounds bad and the general public doesn't understand it. Failing to cordon off the area, locate, and segregate witnesses is also prohibited behavior. This is Police Rookie 101. I'm sure I've missed a few but those stick with me. Valuable experience can be had by exposing Rookie Police Officers to the complexities , sights and smell of a crime scene. Experience that can only be obtained at the side of a more experienced Officer. As the Rookie you are expected to be familiar with those prohibited behaviors. The simple rule for Rookies is keep your hands in your pockets and look with your eyes !
