I was almost hit by a car that then crashed into woodland and stayed as a witness (he was trying to take a roundabout at 60mph). The sarge came over to me, and first question was "are you a triathlete? I am doing my first race tomorrow, any useful tips?)
We also have a bobby on an MTB who potters around and absolutely has his finger on the pulse. He came to see a neighbour who had had some minor building work done that week just to drop a hint that one of the labourers had form, so if anything went missing, get in touch.....
