Factual error: When Mac Taylor's ID card from the Marine Corps is being shown, there are two unintentional mistakes and one probably intentional. First, the design of the ID card in no way resembles an actual DoD issued military ID, but this was probably an intentional mistake by the creators of the show. The picture on the ID however, has two unintentional mistakes. First, Marines are never photographed in their dress blues for official purposes; Mac would have been in cammies or service dress charlies for the photograph. Second, Mac is revealed in several episodes to have been an officer, yet he is shown wearing the dress blues of an enlisted man.
Factual error: Lessing is said to have tried to enter the Marine Corps three times but failed the psych test; no psych tests are given when entering the Marine Corps.
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.
