Continuity mistake: When Holly is first in Grissom's office and says that she feels light headed, Grissom offers her a chocolate-covered grasshopper and takes one for himself. Holly asks, "Is there a grasshopper in there?" and Grissom's right hand is near his waist. When the shot changes, Grissom merely smiles and eats the grasshopper, but his hand started off much closer to his chin without there being an opportunity for him to move it.

The first time we cut to Meg there are tears in her eyes, but her face is dry. The second time we cut to Meg, there is a drying tear track on her right cheek. The third time we cut back to her, the tear track is gone, but there is a tear halfway down her left cheek. This continues throughout the scene.

Continuity mistake: When Nick is staring intently at the doctors lapel area, the camera zooms in and we see some lint on the doctors left lapel. When Nick asks Catherine to get the tape on it, Catherine approaches the suspect and she starts to put the tape on the left lapel, but when the camera zooms in for a close-up of her getting the lint, the tape is being applied to the RIGHT lapel.

Continuity mistake: When Grissom enters the cage in which the woman is found, he goes to the wastebasket to examine the pen that rolled on the floor. As he first picks it up, he grasps it right at the point where the black grip section meets the gray barrel section. As the shot changes and he continues bringing it up to examine it, he is now grasping it near the end of the gray barrel. As it is supposed to be a continuous shot (conversation is uninterrupted the entire time), there is no time for him to change his hand position.
Continuity mistake: When Warrick is talking to Dr. Robins, his collar changes place. During the close-ups, only the right side of his collar is tucked in. During shots farther away, both sides are tucked in.

Continuity mistake: Supposedly, Paul Millander was 10 years old when his father was killed. A newspaper report read by Sara in 1x08(Time 39:45) says this. It also says that his father died August 17th, 1959. In 2x13(Time 43:18), in the last scene, Grissom looks at Paul's birth certificate. It says that Paul was born August 17th, 1956, which would mean that he was actually 3 years old when his father died. (00:39:45 - 00:43:15)

Continuity mistake: Stephanie Watson's supposed killer is, on the TV, named as Mark Kelso, but later when Catherine is going over the DNA sample with Greg, it is a match to a Dwight Kelso - supposedly the same person.
Continuity mistake: When Sara is waiting with Greg for the results for what was inside the tyre that exploded, she grabs the paper straight off the printer, reads it, looks at Greg and takes off immediately to inform Gil. When Grissom looks at the paper, you can see Greg's name is signed at the bottom as confirmation, but he never got anywhere near the paper.
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.
