Character mistake: At the end of the episode when Grissom puts the news clipping up, the word "sacrificed" is spelled as "sacraficed" in the article.
Revealing mistake: At the end of the episode, Grissom pins the newspaper article about the security guard's death onto the bulletin board and the camera zooms in on it. The article is three paragraphs long, however it is the same paragraph of text repeated three times. (A DVD player with a zoom feature can confirm this.) (00:44:30)
Character mistake: When Catherine goes to view Kristy Hopkins' body, she calls Doc Robbins "David", even though his first name's "Albert".
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.
