Over a dozen current and former officers say they believe MPDs Katie Blackwell perjured herself during Derek Chauvin trial Fourteen current and former police officers with the Minneapolis Police Department (MPD) have signed sworn declarations which say they believe MPD Assistant Chief Katie Blackwell perjured herself when testifying in former MPD officer Derek Chauvin’s murder trial. Specifically, the group of former officers say they believe Blackwell perjured herself when she testified in court that the restraint method Chauvin used to subdue George Floyd in May 2020 was not a part of MPD officer training. In that trial, Chauvin was found guilty of second- degree unintentional murder, third-degree murder, and second-degree manslaughter. He was sentenced to 22 years in prison.
However, many say the knee-on-neck restraint Chauvin employed was trained under the maximal-restraint technique (MRT), a restraint the MPD taught and allowed until 2023.
