Character mistake: Nicole Wallace has murdered and stolen the identity of Professor Elizabeth Hitchens, who was Australian. While speaking to Detective Goren she refers to her life in Melbourne, pronouncing it the American way : "Mel-born." No Australian would do such a thing - it is pronounced "Melbun." A detail-obsessed knowall like Goren would pick up on that immediately.
Continuity mistake: Near the end, the detectives give Hawkins the murdered woman's manuscript to read and compare. The stack of papers they give him is easily 300-400 pages thick and held together with a large binder clip. Moments later, in a fit of anger, Hawkins throws the manuscript in the air and papers fly everywhere. The problem is that he throws no more than 50 pages in the air.
Continuity mistake: As Goren and Eames are questioning the Botox guy, Goren takes several syringes from the kit and begins tossing them like darts into the notebook on the table. He does this with at least 5 syringes before the camera angle changes, and when it cuts back to him again there are no syringes in the notebook and he has a fresh handful of them that he begins uncapping and tossing all over again.
Continuity mistake: Goren is interviewing Roger Stern in the cells at the end of the episode. The bars on the cell are straight with curves where the bars cross. In some shots when you look at Goren the bars are bent from one cross section to the next. This changes from shot to shot. (00:34:00 - 00:39:00)
Revealing mistake: Paul Devildis calls the bank to discuss his restructuring plan. During the shots of the two bankers, on the desk is a notebook-sized, plain brown box. It is very distinctive as it is blank except for a single square white label on the front. Later in the episode Paul delivers his restructuring plan with the bomb inside to the bank. It is in this same box.
Factual error: When the cops need to arrest a medical professional, they are frequently shown barging into his/her office, exam room, or even operating room. This would never happen in real life and is strictly forbidden, as it is a gross violation of the patient's privacy, and in the case of the OR, could contaminate the sterile environment, thereby jeopardizing patient safety as well.
