Knights joined
Lincolnshire Police as a
Cadet in 1938, becoming a Constable in 1940 and completed training at the (now defunct) Police Staff College in
Grantham, Lincolnshire. During
World War II, he served in the
Royal Air Force between 1943 until 1945. Knights returned to Lincolnshire Police, reaching the rank of
Chief Superintendent in 1957. He moved to the
Birmingham City Police in 1959 as an
Assistant Chief Constable and rose to the rank of
Deputy Chief Constable in 1970. In 1972 he moved to
Sheffield and Rotherham Constabulary as
Chief Constable. In 1974, Sheffield and Rotherham Constabulary amalgamated with parts of
West Yorkshire Constabulary to become
South Yorkshire Police. Knights returned to
West Midlands Police where he was appointed Chief Constable. He was described as a 'true architect' of the new force, bringing together six separate forces into one.
Controversy In 1983 the
Campaign for Nuclear Disarmament activist Madeline Haigh criticised Knights for not disciplining West Midlands
Special Branch who investigated her after she wrote to a local newspaper complaining about the cancellation of a peace march. Knights defended the case by saying it "fell within the terms of reference of the Special Branch." ==Honours and awards==
