It's pretty interesting that Christopher would be comforted by the actions of the policemen because they resemble the ways fictional policemen behave on TV. What does that say about the way he interacts with the "real world"?

We can understand that Christopher is reassured by the fact that policemen behave in the way he expects. But this almost suggests that he considers the fictional world on TV more "real" than the world in which he actually lives and breathes.
