David, the Assistant Medical Examiner, is looking at the driver's license of Ken Billings, the wheelchair-bound victim who was pushed in front of a vehicle and Billings's birth date is 2/17/1944. David is looking right at this license and says his birth date is 11/9/1952.
When Mickey Dunn, played by British actor Roger Daltrey is apprehended his accent switches back and forth between British and "mobster".
The young Mickey Dunn's eyes are brown, but Roger Daltrey's eyes are blue.
At the visual segue 24 minutes into the show as the camera pans the Las Vegas sky line the cars in the shot are all driving in reverse. The most conspicuous is the large black SUV that is located in the center middle shot backing in the same direction as the camera pans.
The distance between the eyes of the various suspects are the same, but that would be meaningless unless the photographs were all taken from the same distance.--which they weren't.
The crime scene photo of the "low-level mob informant," whose murder forced Mickey Dunn to disappear in 1976, actually shows the aftermath of a hit placed on Carmine Galante, a crime boss in the New York mob. The hit took place in 1979, so that would make it a photo of someone of the wrong mob rank, taken in the wrong location, and dated to the wrong year.
When Catherine is interviewing Mickey at the hospital (final sequence), at one of the flashback scenes showing the car being pushed into the sea, you can see the cable that will be used to pull the car back when scene is done.
Catherine identifies Michael Myers (the horror movie character) as having been in "Halloween, Parts 1-9". Not only is there not a "Halloween 9" (not counting the remake, especially since it hadn't been made yet), but Michael Myers wasn't in Halloween III: Season of the Witch (1982).
