Factual error: (Episode: Sun Block) At the beginning of the episode, all the pool patrons are watching an eclipse, the sky darkens and they watch as the moon passes in front of the sun. The process, from the moon first beginning to touch the sun's disc to total eclipse occurs in approximately one minute. It is impossible for an eclipse to happen that quickly; it would take at least an hour to complete the process shown.
Factual error: When the show begins, a man is run down by a Dodge Charger. The man's injured leg apparently cuts a bio-diesel line under the car. The Charger never was a diesel, and probably never will be. Further proof is at the show opening which showcases a very low-tone exhaust rumble which can only be a gasoline V8.
Factual error: In Natalia Boa Vista's backstory, she states she knew Horatio from her "work with the FBI." But not all FBI agents started as LEOs (law enforcement officers). In her whole time as a CSI, she wields a badge, makes arrests, and interrogates suspects just like a cop (the ONLY 3 characters we know for certain that were LEOs were Calleigh [the flashback episode with Horatio and Jesse], Eric [the flashback episode when Horatio tells Eric to "come see me when you finish the academy"], and Ryan Wolfe, who's fresh off beat patrol when he joins CSIs). In this episode she tells Calleigh she's late to her crime scene because she just picked up her new sidearm and "now I can back you up on crime scenes!" BUT, if she were already a cop she would have been issued a firearm upon graduation. Thus, Natalia (and Walter) were never cops. This show took severe liberties with reality. Real CSIs are no more than expert witnesses, NEVER given the responsibility of arresting or interrogating suspects.
Answer: Yes, sizes of jails differ.
