Cool Change - S1-E2
Deliberate mistake: Willows collects fingernail scrapings from Holly's left hand in the morgue for DNA matching to Holly's shooter. In the flashback, Holly uses her right hand to scratch her assailant while her left-hand remains gloved. (00:32:47 - 00:36:22)
Other mistake: When the CSIs arrive to take in the accident scene from the Pharoah's Fury rollercoaster, the victims are covered in associated wounds and blood, from such a derailing accident. Yet no brain matter seen anywhere. When in a prior take, two of the rail cars had crashed face down into parked cars and pavement. While two other victims were thrown from railcars while in midair.

Grissom's Divine Comedy - S8-E12
Continuity mistake: When Warrick demands to see the hands of a suspect, the suspect refuses and Warrick pushes him up against a wall. During which time, there are multiple angles which show Warrick wearing sunglasses, then suddenly not wearing them anymore. (00:23:30)
Other mistake: When CSI Brown is with the mother of the alleged victim, he shows her a picture of the deceased and asks if she knows her. The name on the picture is the one the mother gives (Simone Molinez). How would the correct name be in the picture if the victim had yet to be identified? (00:17:35)
Continuity mistake: After Natalie lowers the car onto Sara Sidle we know her right arm is pinned and she cannot move it. When Sara hears the coyotes she starts to look around and see where they are coming from. At one point we can see Sara with her right arm inside the crashed vehicle. (00:22:25)

Visible crew/equipment: When David, Warrick and Catherine are standing in the crop circle discussing how the body ended up there, when David says "I have an idea", Warrick looks up slightly and you can see the boom mike reflected in his sunglasses.
Answer: He doesn't have the authority to arrest him - when anyone is arrested in the show, a police officer does it. Also he tells Ty that he is going to be submitting his case findings to Ty's insurance company, who would no doubt contact the IRS, who then would have him arrested for fraud etc.
