Then it would seem that you and left-wing icon, MN AG Keith Ellison, would agree:

Chauvin was arrested on May 29, 2020. Hennepin County Attorney Mike Freeman charged him with third-degree murder, and the lesser included offense of second-degree manslaughter, making him the first White police officer in Minnesota to be charged in the death of a Black civilian. Under Minnesota law, third-degree murder is defined as causing another's death without intent to kill, but "evincing a depraved mind, without regard for human life". Second-degree manslaughter also does not imply lethal intent, but that the perpetrator created "an unreasonable risk" of serious harm or death.
On May 31, Minnesota Attorney General Keith Ellison took over the case at the request of Governor Tim Walz. On June 3, Ellison amended the charges against Chauvin to include unintentional second-degree murder under the felony murder doctrine, alleging that Chauvin killed Floyd in the course of committing assault in the third degree;
On April 20, 2021, a jury, consisting of six White people and six people of color, found Chauvin guilty on three counts: unintentional second-degree murder, third-degree murder, and second-degree manslaughter.
The federal case was not for murder, but for violation of civil rights of both Floyd and a 14yo boy in a separate case:
The United States Department of Justice (DOJ) convened a grand jury in February 2021 to investigate whether Chauvin violated Floyd's civil rights as well as another incident in September 2017 when Chauvin restrained a 14-year-old boy for several minutes, using his knee to lean into the boy's back and hitting him with a flashlight several times. During the restraint, Chauvin ignored the boy's pleas that he could not breathe and the boy briefly lost consciousness. The 2017 incident was deemed inadmissible as evidence in Chauvin's murder trial. Following Chauvin's murder conviction, the investigation was still underway, with the DOJ reportedly weighing whether to bring criminal charges against Chauvin for the 2017 incident.
Federal investigators planned to charge Chauvin and the other three officers for federal civil rights violations, and intended to ask the grand jury to indict him for both the 2017 and 2020 incidents. On May 7, 2021, the U.S. Department of Justice indicted Chauvin, alongside his three co-officers, for constitutional civil rights violations for their involvement in the murder of George Floyd. These indictments caused the state court trial for the three other officers to be pushed back to start on March 7, 2022, from August 23, 2021. Chauvin, also on May 7, 2021, was indicted by the same grand jury for violating the civil rights of the 14-year-old boy he arrested in the aforementioned September 2017 incident. The federal charges were to be prosecuted by Justice Department attorneys in Minnesota and Washington, D.C. On September 16, 2021, Chauvin pleaded not guilty to the charges related to the 2017 incident indictment.
Chauvin pled guilty to the federal charges.
Here's what the sponsor of the moment of silence wants:
Christopher Rocco, a delegate from St. Paul who goes by the name Rocco, proposed the moment of silence on Saturday morning, describing Mr. Chauvin to his fellow delegates as someone “who should get a state retrial, who should get a federal pardon.”
