Revealing mistake: The video that Bitsey watches at the end of the movie, we see David walk over to Constance's dead body on the floor and Dusty walk away to stage left of the video camera. David then immediately turns around and walks towards the video camera, staring right at the lens. As he walks closer, the camera slightly pans down to keep him in the shot.

Dusty would have to have done a quick 90 degree turn, stood on a chair and gotten set behind the camera in a very short period of time - without shaking the table or the camera.
