Didn't we have a recent case of a policeman in Prestatyn who admitted to being a tranny "off duty"?
As for the bulls hit about the dogs tracking her from the scent of the kids borrowed jacket ~ no way! I spent two years working as a dog handler when I first entered the Security business and we only ever used retired RAF Police Dogs ~ most couldn't track their way to the sausage counter. Yes they will react to strange scents or sounds but that is about the extent of it. They are not trained to track but to chase and hold.
Mind ~ as chat up lines go I've heard worse.
