I think people will suprised to note that its actually as a result of intelligence lead policing, than racism.

For example. Someone is mugged. They get a description of a young black man with a black jacket. Police are going to stop and search anyone fitting that description, looking for her possessions.

Because descriptions are typically vague, it does hit ethnic groups harder, as they are less distinguishing features (for example, white people normally have variying hair colours, so reduces the amount of people that would be needed to stop and search).
