According to an article of the Los Angeles Times in 1992, the producers of this movie were the subject of intense surveillance by the Special Investigation Section during the making of the film.
The cloak and dagger man featured on Scott Glenn's visit card and shirts is the actual logo of the Special Investigation Section.
Contrary to the film depiction, Special Investigation Section maintains a high-profile arrest record without incident.
The featured Code 7 bar was a real bar opposite the L.A.P.D. Parker Center in downtown Los Angeles, but it has since shut down.
The weapons used by Scott Glenn are : IMI Desert Eagle .44 magnum pistol, Smith & Wesson .357 magnum Model 27 revolver, Ruger Mini-14 automatic rifle and Heckler & Koch MP5 Kurz model Submachine Gun.
