A pensioner is mugged in a dark alley. two young black men are identified as the muggers in a local youth club. However, the defense claims that the identity parade was not carried out according to correct police procedure.

P.C. Kershaw takes the stand to give details of the arrest of the two defendants. With Mrs Palmer evidence tainted there are now doubts that John Dempsey was the second man. Walter Sissons QC also queries Kershaw's impartiality.

While giving evidence in his defence, John Dempsey claimed that PC Kershaw saw the university student as a black activist and kept him under constant surveillance. He now faces an aggressive cross examination from James Elliot QC
