Mrs Broadhurst spoke of her husband's love of his police work
The widow of a police officer shot dead on duty in Leeds broke down in tears as she took part in a ceremony to unveil a memorial in his honour.
Pc Ian Broadhurst was shot in the head at close range during a routine check on a stolen vehicle on Boxing Day 2003.
Eilisa Broadhurst paid tribute to her husband during a ceremony at the Police Memorial Trust's stone memorial on Dib Lane - the scene of the shooting.
"I know Ian will be looking down on us with great delight," she said.
Former US marine and nightclub bouncer David Bieber is serving a life sentence for the 34-year-old officer's murder.
Mrs Broadhurst told a gathering of family, friends and former colleagues: "Ian's death has affected so many of us in different ways, especially the nature of it.
"As you all know the police force was a big part of who Ian was.
"It was one of the great loves of his life and it allowed him to do what he liked best - fast cars, helping people and getting paid for it.
"The love and support I have received over the past four-and-a-half years has been overwhelming - not only from the police force but from everyone, even those who did not know Ian personally."
The stone was funded by the Police Memorial Trust
Among the floral tributes left at the scene were ones from Gordon Brown and David Cameron.
The prime minister left a note with the flowers which praised the officer's "dedication and courage", while the leader of the Conservatives left a note which said Pc Broadhurst had made the "ultimate sacrifice".
Film director Michael Winner, who attended the ceremony as chairman of the Police Memorial Trust, paid tribute to the courage of Pc Broadhurst and all police officers.
"They fight a war that has no beginning and no end and our debt of gratitude to them is enormous," he said.
"When Ian Broadhurst went to work on December 26, 2003 the spirit that keeps this nation afloat went with him."
West Yorkshire Deputy Chief Constable David Crompton said: "Police officers up and down the country put their lives on the line every day, never knowing what could happen.
"Thankfully few have had to make the ultimate sacrifice made by Ian Broadhurst.
"The permanent memorial is an appropriate way of marking the terrible events that took place here on 26 December 2003, a day which will be remembered as one of West Yorkshire Police's darkest."
Bieber was found guilty of murder in 2004 and originally handed a whole-life sentence.
But in August the Court of Appeal said the facts of Bieber's case, "horrifying though they were", did not justify a "life means life" sentence.
He will now serve a minimum of 37 years in jail.
Bieber was also convicted of the attempted murders of Pc Broadhurst's colleagues, Pc Neil Roper and Pc James Banks.
