Other mistake: Rankin Fitch and his associates are viewing the "Pledge Of Allegiance" scene, and Fitch tells Mr. Lamb "freeze it there" when Loreen Duke is patting Nick Easter on the hand. That camera shot should not exist. Where was the camera for that shot? None of Fitch's goons put a camera up where the Judge's bench would be, so where did that view of the jury come from? That is the only time Fitch et al view the jury from that angle.
Other mistake: When Marley calls Finch after her fight in the apartment, Finch slams the phone down 3 times. The plug for the handset flies up, but the cord was never tight enough to get pulled from the phone.
