On TV, off duty policemen can kill hundreds of people - say they are all bad, and get off scott-free (and usually hook up with some strumpet ex-hooker with a heart of gold).
Troy wears his underpants on his head quite regularly, so I'd be inclined to believe him. Note the part about identifying themselves as an officer (and no doubt flashing the 'ol warrant badge around)? - I'm sure he'd be able to stay off duty, dropping pints and betting on the dish lickers if he kept his yam shut.
That said - I received a yellow sticker in the R. No fine, no loss of points. Just told to get my trumped up charge of the placcard not matching the load weighting on my tyres - fixed.
