The sister of James Ashley, who was shot by a police officer, sent a wreath to Sussex Police headquarters today to mark the fifth anniversary of his death.
Pauline Ashley said she would have delivered the wreath in person but she is expecting her second child.
If she has a boy she intends calling him James in memory of her brother.
Miss Ashley said the family would not rest until it had won justice and she vowed to return to the police HQ in Lewes from her home in Liverpool each year until a public inquiry is held.
Home Secretary David Blunkett, who forced the early retirement of former Sussex chief constable Paul Whitehouse over the shooting, has refused to order one.
Mr Ashley, 39, was unarmed and naked in bed when he was shot dead during a police raid on his flat in St Leonards.
Marksman PC Chris Sherwood was cleared of unlawful killing at the Old Bailey and three senior officers were cleared of misconduct.
Mr Whitehouse resigned on full pension after the Home Secretary wrote to the Sussex Police Authority demanding action to restore public confidence.
Former deputy chief Mark Jordan, who faced disciplinary charges, was retired on medical grounds and full pension.
Miss Ashley, 39, said her family wanted the law changed so police officers responsible for shooting deaths were brought to account.
She said: "No one has been punished for the death of my brother and we won't go away until someone is.
"We also want a full and open public inquiry."
A force spokesman said Chief Constable Ken Jones planned to meet the Ashley family in the near future.
