The reception of the 'hotel' the leads stay in has a big sign in the window saying 'Suffolk County Council', which they make no effort to conceal in a number of shots.
Agent Smith called the Police Officer in charge "Lieutenant". There are no Lieutenants in the British Police Force. Also, she pronounced it "Lootenant" but she was English, and in London, so she would have pronounced it "Leftenant".
