Factual error: When the Joan Cusack character bolts into the control room with the "Mercenary" cassette, you can here the director counting down to roll the tape. A 3/4" tape being inserted and threaded up in the machine normally takes about 8 to 10 seconds, yet the tape plays when the operator hits the play button.
Plot hole: How could Jane not be aware that Tom had only used one camera for the date rape interview, recording his fake tears later? That's the way things are done on television news shows and as an experienced, hard-bitten television producer she could not possibly be unaware of that. The reporter always records his or her reaction shots (called 'noddies') after the interviewee has left. Shooting with two cameras would involve two crews, two lighting rigs, a vision switcher and so on and so on and a straightforward interview simply would not justify such a complex and expensive set up.
