THE FORMER POLICE officer found guilty of murdering George Floyd has appealed against his conviction.

Derek Chauvin’s appeal centres on, among other issues, that the jury was intimidated by protests and prejudiced by excessive pre-trial publicity.

Chauvin asked the Minnesota Court of Appeals to reverse his conviction, reverse and remand for a new trial in a new venue, or order a resentencing.

Last June, Hennepin County Judge Peter Cahill sentenced Chauvin to 22-and-a-half years in prison after jurors found him guilty of second-degree murder, third-degree murder and second-degree manslaughter.

Floyd died on May 25, 2020, after Chauvin pinned the black man to the ground with his knee on his neck for nine minutes, 29 seconds.

The victim had been accused of passing a counterfeit 20 dollar bill at a convenience store. Three other officers were also charged in the case.

Chauvin’s lawyer, William Mohrman, laid out a number of challenges to his conviction, including his long-standing argument that the trial should not have been held in Hennepin County, where Mr Floyd was killed.

“The overwhelming media coverage exposed the jurors — literally every day — to news demonising Chauvin and glorifying Floyd which was more than sufficient to presume prejudice,” the brief said.

In the months that followed Floyd’s killing, protesters took to the streets in Minneapolis and around the country to protest over police brutality and racism. Some of that unrest was violent.

Mohrman said several potential jurors expressed concerns during jury selection that if Chauvin was acquitted they would fear for their personal safety and worried about more violence.

He said several of them indicated they were intimidated by the security measures implemented at the courthouse to protect trial participants from protesters.

The filing also cited the fatal shooting of Daunte Wright by a police officer in nearby Brooklyn Centre, during Chauvin’s trial.

It says jurors should have been sequestered after selection to avoid being prejudiced by reports of that slaying. It also cited a 27 million dollars settlement reached between the city and Mr Floyd’s family that was announced during jury selection, saying the timing of that prejudiced jurors in the case.

Mohrman cited several instances of alleged prosecutorial misconduct, claiming untimely sharing of evidence, failure to disclose and document dumping by the government.

The filing also says the judge did not apply the sentencing guidelines correctly and should not have included “abuse of a position of authority” as an aggravating sentencing factor for the former police officer.

Minnesota Attorney General Keith Ellison has 45 days to respond to Chauvin’s brief.

The appeal came as the Minnesota Department of Human Rights released the results of a nearly two-year investigation launched after Mr Floyd’s slaying.

It found the Minneapolis Police Department has engaged in a pattern of race discrimination for at least a decade, including stopping and arresting black people at a higher rate than white people, using force more often on people of colour and maintaining a culture where racist language is tolerated.
