The photo was taken circa 1973 at a ‘continuation course’ at Ryton On Dunsmore District Police Training Centre. I will leave the readers to guess where I might be in the picture. The definition pages show some of the formality of learning that we undertook as probationer constables in those days learning the definitions ‘parrot fashion’ and being very much a part of a disciplined organisation. The two little books ‘One In For D & D’ and ‘It’s A Blag – the dark art of police humour’ provide a little insight into the ‘not so formal’. All parts of the ‘glue’ which bound us together. The ‘thin blue line’ that was routinely stretched but never broken.
