You are the first to arrive on the scene of a violent crime. When the sergeant arrives he asks you to take photos, and another officer, one more senior than yourself is assigned to assist you by writing up the photo log as you take the pictures. As you are taking photos, you notice that the assisting officer is smoking a cigarette and drops the cigarette butt on the ground, in the crime scene area. You also notice that he is lighting up another cigarette. What will you do?
