Wallander arrives at a scene in the passenger seat of a police car. He exits and in the next scene when he walks from the car no one is sitting in the drivers seat.
When the Major reveals his bomb, he says that if he lets go off the trigger then the bomb will go off. However later in the car when Wallander has just exited, the Major takes on his beret, one can clearly see that he is not holding any trigger.
In one scene at the police station you see one of the screens showing a traffic surveillance system with live view. Just before the scene ends the video on the screen starts to rewind the picture.
