Nguyen sentence to be appealed Constable Bill Crews, who was killed in a gunfight. Photo: Police Media The NSW Director of Public Prosecutions will appeal the minimum seven-year jail sentence given to Sydney man Philip Nguyen over the shooting death of NSW Police Constable Bill Crews. The family of Constable Crews has expressed great disappointment over the sentence handed down by Justice Elizabeth Fullerton earlier this month over the 2010 shooting, in which one of Constable Crews fellow officers accidentally shot him in the back of the neck while returning fire after Nguyen initiated a gunfight. Police Commissioner Andrew Scipione publicly stated that he believed the sentence was inadequate. Disappointed with sentence ... the parents of Constable Crews, Kelvin and Sharon Crews Photo: Nick Moir On Thursday, NSW Attorney-General Greg Smith said he had now been informed by the Director of Public Prosecutions that it would be appealing the sentence given to Nguyen, who pleaded guilty to manslaughter over the shooting. On the day of the sentencing hearing, the court heard Constable Crews was one of eight officers who went to the Bankstown car park in the unit block where Nguyen lived to carry out a search warrant. The operation had been deemed to be of low risk. But, as Constable Crews and another officer moved towards the garage, the 26-year-old was heard yelling: "Gun, he has a gun." There was then a sequence of five shots fired from three guns in the space of seconds, with Nguyen firing the first shot, hitting Constable Crews in the arm. In return, Constable Crews fired three shots before a fellow detective fired once, accidentally shooting him in the neck. Supreme Court judge Elizabeth Fullerton said although Nguyen "didn't fire the shot that killed him, he caused his death." The court heard Nguyen, a Vietnamese refugee, believed Constable Crews and the other officers were robbers. Outside the court, Constable Crews' father, Kelvin Crews, expressed disappointment at the sentence, saying his son had given his life in the line of duty while his family had been sentenced to life.
