Thousands from all walks of life turned out for the day-long ceremonies here on Wednesday to honour slain Indian-American police officer Sandeep Singh Dhaliwal, who was shot dead on duty during a traffic stop.

Dhaliwal, 42, was the first Sikh sheriff’s deputy in Harris county with a population of over 10,000 Sikhs.

He made national headlines when he was allowed to grow a beard and wear a turban on the job.

He was gunned down while conducting a routine mid-day traffic stop in northwest Houston on Friday.

The fallen deputy’s funeral included processions, a traditional Sikh funeral and a law enforcement funeral with a 21-gun salute from fellow officers and a helicopter flyover.

As Amazing Grace was played on bagpipes, members of Harris county sheriff’s office (HCSO) folded the American flag that covered his casket and Sheriff Ed Gonzalez presented it to Dhaliwal’s widow Harwinder who clutched it to her heart.

After final ceremonies from the law enforcement memorial service, the Dhaliwal family and members of the HCSO headed to the Winford Funeral Home for a closed cremation.

The procession route was lined with blue and white signs reading “Always in Our Hearts”, and “In Loving Memory of Deputy Dhaliwal”.

People had posted custom yard signs, billboards and flowers all along the route and in the neighbourhood.

At the service, Simratpal Singh, a US Army captain, flanked by other members of the Sikh community in military service, described Dhaliwal as “humble, fearless, not dissuaded by negativity”.

“Our lion may be gone physically but his legacy of selfless service and of breaking down barriers will continue to live,” he said.

Senator Ted Cruz, speaking before thousands during the Sikh part of the ceremony, addressed Dhaliwal’s widow and their three children in saying the community “supports you and lifts you up”.

“We are grateful for your father’s service, and his sacrifice and his legacy,” Cruz said.

Dhaliwal joined the force 10 years ago and was the state’s first law enforcement officer to receive permission to wear a religious turban and beard while on duty.

Commissioner Adrian Garcia who hired Dhaliwal 10 years ago said the stadium full of people and the deputy’s celebration of life was “fit for a king”.

As he addressed Dhaliwal’s father, he said, “Baba, you raised a good man. You raised him with a heart of gold. It is unfair that a father should outlive his son.”

Lt Gov. Dan Patrick said he doesn’t normally speak at public funerals but he was honoured to be invited to speak at Dhaliwal’s funeral.

“Since 2015, we’ve lost 50... 50 men and women of law enforcement in the line of duty and deputy Dhaliwal was the 50th,” he said.

“He (Sandeep) did more in his life than some people do in a hundred years,” he added.

Houston mayor Sylvester Turner said it was “moments like these when we fall on our faith.” “He (Dhaliwal) was the ambassador of all that is good. And the way he died does not erase that,” Turner said.

“In a city that happens to be the most diverse in the country, is a city, because of this one person, on this day and hopefully days to come, will be the most unified it has ever been,” added Turner.

Gonzalez said Dhaliwal was a trailblazer and wore his Sikh faith on the outside for all to see. “Sandeep was an inspiration to us all.”
