It is day seven of the testimony of former Minneapolis police officer Derek Chauvin, who was charged with the death of George Floyd.

Here is what they said yesterday in court::

Minneapolis Police Chief Medaria Arradondo Thoroughly opposed Chauvin’s actions during Floyd’s arrest last May in violation of department policy. “As soon as Mr. Floyd stopped resisting, and certainly once when he was in need and tried to verbalize it, it should have stopped,” Arradondo testified.

The boss said Chauvin’s kneeling on Floyd’s neck for nine minutes and 29 seconds was not a trained tactic and violated guidelines on de-escalation, the objectively sensible use of force, and the requirement to provide assistance. In his testimony, Arradondo described the department’s training programs and the core value of treating everyone with “dignity and respect”. He said officials must be familiar with the guidelines, including de-escalation and the use of force.

Last year Arradondo fired Chauvin and three other officers who were involved in Floyd’s death. He said this was “murder”.

Dr. Bradford Wankhede Langenfeld, an emergency doctor at Hennepin County Medical Center, said he treated Floyd for about 30 minutes on May 25, 2020 when hospital staff tried unsuccessfully to restart his heart. Based on the paramedics’ reports and Floyd’s health, Langenfeld said the “more likely possibility” of Floyd’s cardiac arrest was hypoxia or lack of oxygen. In cross-examination, Langenfeld said that hypoxia can be caused by many things, including drugs like fentanyl, methamphetamine, or a combination of both.

The doctor’s testimony goes back to the prosecution’s argument that Chauvin’s kneeling was a major cause of Floyd’s death. However, Chauvin’s attorney has argued that Floyd died because of his drug use and other health problems.

Minneapolis Police Inspector Katie Blackwell, who recently acted as commander of the department’s training division, said officers in her medical department have been trained on the dangers of positional suffocation and the need to get someone on their side or sit up to recover. Officers are also trained to provide medical assistance to suspects.

Blackwell looked at a photo of Chauvin on Floyd’s neck and testified that it was inconsistent with the department’s training. You train with a one-armed or two-armed neck support. “I don’t know what an improvised position that is,” she said. “It’s not what we train.”
