It was actually a lot more helpful to have Calvin Hart, a cop, as my template. He was also my technical advisor on Shaft. This time, I kinda got to go to Jersey City with him, and hang around, and watch him interact with other cops, people in the projects, and see what it means to be him. People call him 'Big Daddy' and he's this larger-than-life hero to a lot of people.
