Do you really want to contract to an organisation that can arrest you on a whim? No, the correct answer is no. You want danger money to help the police. (Cough) Cleveland (cough) Constabulary. Offered to show me all the porn they'd seized. "No ta, I have a long drive home". Lit up a joint in their drugs room. "Aye fine, this is going to take some time - as long as you are sure about me driving home".
