Recently I was stopped by an unmarked police car and accused of using a hand-held mobile phone whilst driving. In fact my Peugeot has built-in handsfree and in any case my phone was in my pocket and certainly not in use. This accusation resulted in a vehement denial from me and an intransigent position taken by the two officers. When I drove off I wasn't overly concerned since I thought I could obtain the call records from my phone provider but it is now proving a problem to obtain them and a friend has also pointed out that they may just claim that I was using another phone. Where do I stand on this? How do I prove that these two traffic officers need their eyesight checked?
