Factual error: When discussing a recent search of a suspect's home, Hill Harper says "we got his hard drives", but pulls a computer power supply out of a bag. Hard drives are significantly smaller and don't have a bundle of wires coming out the back of them.
Character mistake: When talking about Mike and Ike giving them descriptions while on NZT, he mentions that he once heard Ike's name but forgot it. Completely impossible since his memory is impeccable on NZT.
Other mistake: When Brian is using the right computer and thinking about the murderer of Paul Wilkerman, the computer screen is turned off. (00:31:40)
