The GPD in the Nolan films is heavily modeled on the New York City Police Department. Patrol cars are painted in a modified version of a paint job used by the NYPD in the 1980s and 1990s. In a flashback scene shortly after the deaths of Bruce's parents in "Batman Begins", Gordon and other officers are shown wearing sky blue uniforms, similar to those worn by the NYPD from the 1970s through the mid-1990s. In all present-day scenes, patrol officers wear black uniforms. The text on patrol officers' shoulder patches, as well as various modified versions of the logo such as the seal used on SWAT trucks, establish the force as being first established in 1820.
