At the recent Social Inclusion Network meeting, Constable Jim Scotson, the Hate Crime Officer for Merseyside Police based St. Helens, described the work of the Hate Crimes Unit, which is locally known as the ‘Sigma' unit. <--break->The title of Sigma was carefully chosen. Sigma is a letter from the Greek alphabet and symbolises the work of the unit in recognizing and protecting all vulnerable members of our society whilst seeking to continuously improve the service the police provide to victims.
