Hertfordshire's Police and Crime Commissioner has scrapped a diversity guide that advised officers against using certain words and phrases. The guide, which called for gender neutral language and discouraged the use of terms like 'blacklisted' and 'black sheep', was criticized for being 'virtue signalling' and damaging public trust. The commissioner and the Chief Constable have commissioned a review of similar documents. Critics argue that the guide is unnecessary and excludes certain perspectives. The police forces maintain that the guide was intended to promote respect and understanding.
