I recall these histories not to obsessively comb over the past, but simply to know it. Perhaps I am betraying my ignorance, but until I went actively digging for black British histories, I didn’t know them. I had heard that black people in Britain had always had a difficult relationship with the police. But I didn’t ask why this was the case. It made more sense to me once I understood that innocent people had died, that homes were broken into with scant evidence for searching them, that teenagers and young adults were frisked in a ritual of humiliation.
