Plot hole: At the very end of series two, there was a shootout during an armed robbery. WPC Granger somehow had access to a firearm. Surely the fact of her uniform rank would not have allowed this.
Plot hole: Series 1, Episode 7: Alex has a car wrecked by having a tank driven over it. She is seen in the turret, so who was behind the wheel?
Answer: Have you finished watching the entire series? I don't think it's fair to answer this for someone who hasn't.
