The numbers on the door (56) before they place the entry explosives, are different to the numbers on the blasted door that DS Arnott examines on the ground revealing the "6" to be an upside down "9". The former are neatly on the door and are smooth with one visible screw hole, the latter are rusted and loose with more visible screws. The target door, also 56, shows screws in positions that are different to the blasted door and would not pivot the same as the numbers that DS Arnott moves into place to show the error.
