14 police officers have signed sworn declarations that disagree with the training officer's testimony that the restraint technique was not part of training. She was promoted to Assistant Chief after her testimony.
"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."
“With this motion, 33 former MPD officers who served with Blackwell, and one who currently serves with her, have sworn that MPD trained this restraint as part of the ‘maximal-restraint technique’ (‘MRT’) and otherwise. Indeed, 14 of these officers have sworn—under oath—their belief that Blackwell perjured herself,” wrote attorney Chris Madel in this week’s motion."
There are also training pictures available of 1 of the charged officers practicing the restraint.
