The below picture is one that I often use when teaching The CP Journal's Tactical Analysis class to police officers that demonstrates how behavioral analysis not only helps police officers identify people of interest, but to communicate exactly why that person is important. The picture is of onlookers to a Los Angeles gang shooting and was taken just as the first responders were arriving on scene. I typically lead the class through a discussion that ends with the students establishing expectations for what they think they would encounter before I even show them picture. The goal is for them to simulate what would be going through their head if they were the officers who had gotten the call to respond to this type of situation and to be able to arrive on scene with an anticipated baseline already established. Students find themselves not only thinking through the different clusters of behavior that they might observe (dominant, submissive, uncomfortable, or comfortable) but also the different causes for each type of behavior and why those different reasons are important
