About 20 years ago my now son-in-law was in his mid twenties and working in a bank in Leeds. He is a bit of a petrol-head and scrimped to own an up-market car.
He was in charge of locking-up the bank for a few weeks. One evening after he left he became aware of a large car following him. He speeded up, it followed. Alarmed, he tried to lose it, thinking a bank robbery was the motive. Eventually another car stopped him. It was the police thinking it was suspicious that such a young man was driving such a car. He proved his bona fides and they then tried to charge him for speeding (which they had caused). It was eventually thrown out of court when the bank weighed in.
He is very fair-skinned, blond and with blue eyes. Nothing to do with race at all. The police could be charged with stereotyping - but not racially. Some people are over-sensitive.
