Full justice can only be served if Daphne’s killers receive the punishment that fits their crime - the murder of a mother by criminals who were willing to blow up her family with her to make sure she is killed.
Justice for Daphne Caruana Galizia means her murderers should not be pardoned. Past crimes should not be cashed as currency for killers to escape justice for murder.
Crimes should be solved and criminals brought to justice, but not at the expense of denying Daphne the justice she deserves. She has already given too much for that.
