Stupidity: The plan to infiltrate Emma into the coroner's office in a body bag is stupid. She is wearing a paramedic's uniform, and we see later when Mickey arrives, nobody is checking ID papers. How would she know that there was nobody in the room when she emerged from the body bag? If she could walk about the building without being stopped, why couldn't she simply walk in through the wide open front door in the first place?

Stupidity: Emma and Sean conned Neil Ryder out of £30,000 by selling him a Porsche, which is just an empty shell. It has no engine, gearbox, or drive chain. Are we really to accept that someone pays £30,000 in cash for a car without even starting the engine, let alone taking it for a test drive?
