Revealing mistake: Season 5, episode 8, "My Name is Mac Taylor": When the killer sets himself on fire, he's not wearing any gloves. In the next shot he is, to protect the stuntman from the flames.
Revealing mistake: Season 5, episode 18 "Point of No Return": When Danny fires at the bad guy, there are sparks coming from the metal pipes when his bullets hit them. One of the things causing the sparks burns too slowly, taking over a second before it fades out.

Revealing mistake: When Mac shows Stella the photo of The Professor and her "mother", you see that it is the actress (Melina Kanakaredes) with a wig on.
Revealing mistake: At the end of the episode, Jamie Sunderland receives a message from her father to not look back. The closeup on the phone's display shows that the phone is offline and it is visible that the message is in fact a wallpaper.
Suggested correction: Theoretically correct, but it can be argued that the only evidence present is the bullet (which has DNA and prints burnt off when fired) and the body (which can only be handled by the MEs) gloves are not required.

What utter rubbish. No CSI would enter a crime scene without first putting on latex gloves - it is a carved-in-stone rule.
Exactly. Since Mac, Stella and Danny were processing a crime scene, they would need to wear gloves because without them, they would have contaminated a crime scene by not only getting their fingerprints over everything but, if one of them got a cut or scrape, their DNA would also be thrown into the mix and any defense attorney can call them out on their carelessness and have any evidence thrown out.
