Continuity mistake: The whole time sequence in the last part of the movie is messed up. After trying to nab the bad guys at the hotel, Tom Selleck goes home and puts his son to bed, then is called back in to work, and then the rest of the film is supposed to be the same evening, but it was already late night.
Plot hole: Considering Luther is responsible for the death of 6+ people and 2 cops, there is no way there would not have been a small army of cops including 2 or more snipers covering the restaurant stakeout. There is no way he could have murdered Jackie and then just run off into the bushes.Grumpy Scot
Luther: I watch, I look, I listen. I'm watching you now.
Ramsay: Right. What's on your mind, Luther.
Luther: You're standing by the desk punching buttons on the console, trying to trace this call, which won't do shit! Because I'm calling from a mobile phone. Now you're looking around... Now you're cupping your hand over the receiver.
Ramsay: He's tapped into the closed-circuit TV.
