Season 1 generally

Plot hole: The car was tracked down by finding the original car key on Jimmy's body. If he had stolen the car from the original owner, how did he come to have the original car key?

Season 2 generally

Factual error: Both detective superintendents always wear uniform, which is only worn by detectives on very formal occasions if at all. Both also wear collar badges, which are not worn by either the Metropolitan Police or Thames Valley Police, the forces to which they belong.
