Hammer Down - S6-E7
Dr. Ray Langston: You know that the, uh, oldest projectile fired from a weapon was recorded in the fourth century in Japan? It was fired from a very crude handheld cannon that you lit with a wick. Its sole purpose was for taking life. Seems that after seventeen hundred years of evolution...[pumps shotgun]...we haven't come very far, have we?
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.
