A police officer accused of murdering the ex-footballer Dalian Atkinson was "not honest" in police interviews or in the account he gave in court, the prosecution has told jurors.
Alexandra Healy QC said PC Benjamin Monk's apparent lack of memory was "a barricade to shelter behind".
PC Monk denies murdering Mr Atkinson outside the ex-footballer's father's home in Telford on 15 August 2016.
The 43-year-old also denies a charge of manslaughter.
Another police officer who was on duty with PC Monk that day, 31-year-old PC Mary Ellen Bettley-Smith, denies assaulting Mr Atkinson with a baton.
