Rows of police officers saluted in silence as the coffin carrying Detective Inspector Anderson emerged from inside St Patrick's Cathedral, quietly shedding tears for their fallen comrades.
Draped in an Australian flag, the respected fallen officer was carried out on the shoulders of those he served with for so many years.

Standing closely behind was a grieving widow and her distraught children.
Killed doing his job, which he loved; Detective Inspector Bryson Anderson was laid to rest this afternoon with full police honours.The moving service was a fitting farewell for a man who made the ultimate sacrifice.
But for some the emotion and heat was too much. It is believed a number of people collapsed during the service.
Inside the church, fellow officers, government officials and dignitaries joined with family and friends to say goodbye and honour the 45-year-old husband, father, son and policeman.
Outside, thousands of people lined the streets and bowed their head in unison to show their respects to the veteran officer who lost his life trying to protect others.
An outside broadcast and a white marquee was also set up to accommodate the massive crowd of mourners.
The service included a number of salutes, paying homage to Detective Inspector Anderson's service as an officer.
While Detective Inspector Anderson’s devotion to his job was commended, his good-natured attitude towards his family and community was also highlighted.
"Bryson lived for his community and died serving it," NSW Police Commissioner Andrew Scipione said.
Commissioner Scipione also presented the late Detective Inspector Anderson with two awards during his eulogy; a National Police Service medal and the Commissioners Valour Medal, an award given to an officer who demonstrates an act of conspicuous courage and exceptional bravery
Eulogies were then given by Det Insp. Anderson's brothers Damian and Warwick Anderson and his wife Donna.
"Today is the 12.12.12," Mrs Anderson said.
"They say there will never be another day like this in a thousand years. I hope for the sake of my family and for the sake of the police family it doesn't happen again.
"He will always be remembered."
His brother Damian spoke of Bryson, the family man.
"To Warwick and I, Bryson was our our brother, to mum and dad he was their baby son.
"Bryson, we will miss you."
The fallen officer's children Darcy and Olivia took a page from their late fathers book and braved the gathering to say a reading in honour of their father and his colleagues.
More than 1000 uniformed police were among the mourners that packed the Parramatta cathedral, including NSW Police Commissioner Andrew Scipione, Minister for Police and Emergency Services, Michael Gallacher, Premier of NSW, Mr Barry O’Farrell and Governor of NSW, Marie Bashir, AC, CVD.After the church proceedings, a funeral procession with marching escorts closed Victoria Road between Church and O'Connell Streets.
As the vehicles left the cathedral, Det Insp.Anderson's youngest son gave a short wave of acknowledgment to those who had gathered.
And as one final mark of respect Polair helicopters conducted a low level fly past.
On the ground mounted units, police band, VIP cycles, family cars, uniformed non-commissioned and commissioned officers escorted Detective Inspector Anderson to his final resting place.
