Audio problem: When Sid hands Mac the test tube with the metal splinter, Mac says "Looks metallic". There is a full frontal shot of Mac's face, and his mouth doesn't move.
Green Piece - S5-E17
Audio problem: Season 5, episode 17 "Green Piece": When Stella is typing on the Apple keyboard she hardly lifts her fingers from the keys, yet we hear a loud clicking sound. That type of keyboard doesn't make that kind of sound, unless you pound the keys with great force. Also, the clicking sounds don't match up with her keystrokes.
Audio problem: Season 5, episode 18 "Point of No Return": When Hawkes is talking to Mac about the fibers he found, there's a brief shot of his silhouette in which his lips don't move while talking.
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.
