Today’s statement from the home secretary has revealed shocking action by the police. The public inquiry which has been announced will deal with undercover policing, but concern should go much wider, to police race relations generally. The inquiry will lead to public confidence in the police being damaged further. Police failings revealed will be woven into a long history of poor relationships between the police and black people. That history is not about the past, it lives today, seeping away public trust in the police.
