A new TV show on the Fox Network entitled The Following is described as:

The Following stars Kevin Bacon as retired FBI agent Ryan Hardy, who is called in to deal with serial killer Joe Carroll (James Purefoy), who he captured nine years ago. While Carroll is trapped in prison, he has spent the last nine years using the Internet to recruit an army of like-minded killers to carry out his objectives… and only Ryan can stop him.

Viewers with a keen eye will note that the FBI utilizes a command unit which is none other than the former Oak Lawn Squad 1. No longer painted red, the unit is white over blue and has had an exterior awning added.
