The mother of Azelle Rodney, who was shot dead by a police marksman nine years ago, has criticised the Crown Prosecution Service for the "intolerable" delay in making a decision on criminal charges.
Susan Alexander has written to the CPS telling them that "no mother should have to go through this".
Mr Rodney was shot six times when officers stopped a car he was travelling in with two other men in Edgware, north London.
The officer who fired the fatal shots, known only as 'E7', lost an appeal against a public inquiry finding that he had used excessive force when he shot Mr Rodney.
His lawyers argued that the police had intelligence that the men in the car were carrying machine guns and that the officer had fired because he thought Mr Rodney was about to shoot him.
