Actually it make sense. Looking at the figures in this report https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/480250/bulletin.pdf https://www.gov.uk/government/uploads/system/uploads/attachm... - see for example chart 3.09 and 3.11, whites tend to be murdered much more by people they know / in their home. Therefore it's more likely that a white murder victim was killed by someone they know - hence likely to be solved & convicted. Blacks have (relatively) higher chance of being killed by strangers outside - hence lower probability of arrest & conviction.
