Three teenagers have been jailed over the killing of PC Andrew Harper.
Henry Long, 19, and Jessie Cole and Albert Bowers, both 18, had denied murder. Long admitted manslaughter and his co-accused were found guilty of the same offence by a jury at the Old Bailey in central London last week.
Long was sentenced to 16 years in prison, and Bowers and Cole handed jail terms of 13 years each.
PC Harper was dragged for a mile behind their car, after he tried to stop the group towing away a quad bike, stolen from outside a house in Berkshire in August last year.
The judge, Mr Justice Edis, said on Friday his role was to impose a sentence against the teenagers responsible for PC Harper’s death which reflected “the seriousness of this case and protects the public”.
He described the killers as “young, unintelligent but professional criminals”, and said none of them had “shown anything resembling remorse”.
The 28-year-old Thames Valley police officer’s grieving widow, Lissie Harper, said she was “utterly shocked and appalled” at the decision not to convict the trio of murder.

The pair were childhood sweethearts and had been in a relationship for 13 years.
She has since called on the government to intervene, despite a retrial being unusual.
Reading out her victim impact statement, she described to the court the “indescribable trauma” of being “robbed” of a future with her “soulmate”, and finding herself in “a lost and endless world” following her husband’s death.
“My life often feels bleak, hopeless, irreparable,” she said, breaking down twice as she spoke.
“Not only did these men take this man from me, they took our future too,”
“They took more than one life away that day, they stole the person I used to be.
“I am now a shadow of the person I once was. Broken, distraught, beaten, a void, an empty shell.”
Deborah Adlam, PC Harper’s mother, added in her victim impact statement: “I have sat in the mortuary of my son’s covered body, too damaged for me to see. He was our first-born child and he has been ripped from me.”
