While getting Eddie up the stairs with the rope, Richie throws the rope through a pulley with the end not attached to Eddie. The next shot shows Richie pulling the rope and Eddie being pulled towards the stairs. This would be impossible because the part of the rope put through the pulley, when pulled, would only make the rope fall out and not at all move Eddie.
PC Jones wears chevrons which denotes the rank of Sergeant, not PC (Police Constable).
It's odd how the police aren't summoned when the flat window is shattered, or hearing the furniture being overturned, or even the gunshots.
During the scene where Richie gets Eddie ready for bed, in Burglary, and is pulling on the rope, a crew member's hand can be seen tugging in the shot of Eddie by the staircase.
