Justice Department to probe policing in Minneapolis after ex-officer Derek Chauvin found guilty of George Floyd's murder

ITV News Security Editor Rohit Kachroo speaks to emotional residents in Minneapolis after the George Floyd verdict

A sweeping investigation into policing practices in Minneapolis is being opened by the US Justice Department after former officer Derek Chauvin was found guilty of the murder and manslaughter of George Floyd.

Mr Floyd died in the Minnesota city in May after Chauvin knelt on his neck during an arrest for more than nine minutes.

After the 45-year-old was convicted on Wednesday, crowds reacted with joy and relief, with many feeling it marked a watershed moment in race relations in the US.

A woman bursts into tears as she says "they see us" upon learning about Chauvin's guilty verdicts:

The death of Mr Floyd, who was black, prompted months of Black Lives Matter protests across the world and mass demonstrations against policing in the US.

The Justice Department is already investigating whether Chauvin and other officers involved in Mr Floyd’s death violated his civil rights.

“Yesterday’s verdict in the state criminal trial does not address potentially systemic policing issues in Minneapolis,” Attorney General Merrick Garland said.

The investigation is known as a “pattern or practice” — examining whether there is a pattern or practice of unconstitutional or unlawful policing — and will be a more sweeping probe of the entire police department and may result in major changes.

It will examine practices including use of force, and whether the department engages in discriminatory practices.

It will also look into the department’s handling of misconduct allegations and its treatment of people with behavioural health issues and will assess the department’s systems of accountability, Mr Garland said.

It is unclear whether the years under investigation will begin when Mr Floyd died or before.

Minneapolis Police Department is also being investigated by the Minnesota Department of Human Rights, which is looking into policies and practices over the last decade to see if it engaged in systemic discriminatory practices.

Mr Floyd was arrested on suspicion of passing a counterfeit $20 note for a pack of cigarettes at a corner shop.

The 46-year-old panicked, pleaded that he was claustrophobic and struggled with police when they tried to put him in a patrol car.

They put him on the ground instead, where Chauvin then knelt on his neck.

The centrepiece of the case was bystander video of Mr Floyd, with his hands cuffed behind his back, gasping repeatedly: “I can’t breathe”, and onlookers shouting at Chauvin to stop as the officer pressed his knee on or close to Mr Floyd’s neck for what authorities say was about nine-and-a-half minutes, including several minutes after Mr Floyd’s breathing had stopped and he had no pulse.

Mr Floyd’s death on May 25 became a flashpoint in the national conversation about the deaths of black Americans at the hands of law enforcement and sparked worldwide protests.

During the trial, Chauvin’s lawyer persistently suggested his knee was not on Mr Floyd’s neck for as long as prosecutors argued, suggesting it was across his back, shoulder blades and arm.

President Joe Biden has promised his administration will not rest following the jury’s verdict in the case, saying much more needs to be done.

“‘I can’t breathe.’ Those were George Floyd’s last words,” Mr Biden said.

“We can’t let those words die with him.

"We have to keep hearing those words.

"We must not turn away.

"We can’t turn away.”

The Justice Department had previously considered a pattern or practice investigation into the police department soon after Mr Floyd’s death, but then-attorney general Bill Barr was hesitant to do so at the time, fearing that it could cause further divisions in law enforcement amid widespread protests and civil unrest, sources told the Associated Press news agency.

Mr Garland said the challenges “are deeply woven into our history”.

“They did not arise today or last year,” he added.

“Building trust between community and law enforcement will take time and effort by all of us, but we undertake this task with determination and urgency knowing that change cannot wait.”
