After going through his own resume, Arradondo described the department's training programs and the core value of treating everyone with "dignity and respect".
The chief said it's important for his officers to meet the community where they are, and said they need to respond in a way that meets "what our community needs".
The trial is expected to turn toward the officer's training Monday after the first week was dominated by testimony from eyewitnesses into the incident and George Floyd's death. "Chauvin knew what he was doing".
Among the group were an off-duty Minneapolis firefighter and EMT-who said she was ignored after repeatedly offering her assistance-as well as an MMA fighter who tried to explain that Chauvin's chokehold was cutting off Floyd's circulation.
With that groundwork established, the prosecution is expected to focus on proving Chauvin's actions that day should be considered murder and manslaughter. Instead, he told his manager, and one of Martin's coworkers later called the police - setting into motion a chain of events that led to Floyd's death.
Some of that use of force analysis has already entered the trial.
Judge Cahill ruled that testimony must be limited to use of force, crisis intervention and medical training, adding, 'Then we're done with the MPD people giving opinion regarding use of force'. Several teenagers also testified how they begged the officers to stop as Floyd was "gasping for air."When paramedics finally arrived at the scene, Chauvin had to be instructed to get off Floyd". "It would be reasonable to put a knee on someone's neck until they were not resisting anymore, but it should stop when they are no longer combative".
Genevieve Hansen leaves the Hennepin County Government Center after finishing her testimony in the trial of former Minneapolis police officer Derek Chauvin on March 31, 2021, in Minneapolis, Minnesota. The defense claims that Chauvin was merely following his training as a police officer.
He said testimony from early last week was the most compelling.
Speaking softly and soberly he recalled, 'In the absence of any apparent reversable cause, [I felt that] the likelihood of any meaningful outcome was far below 1 percent and we would not be able to resuscitate Mr Floyd, so I then pronounced him dead'.
Dr. Bradford Langenfeld, an emergency medicine physician, said he treated Floyd for about 30 minutes on May 25, 2020, as hospital staff unsuccessfully tried to restart his heart.
This may help prosecutors, who have suggested they will argue that asphyxiation was the cause of Mr Floyd's death - contrasting the ruling of the medical examiner who said Mr Floyd died of "cardiopulmonary arrest", which means a person's heart and lungs have stopped.
"Doctor, is there another name for death by oxygen deficiency?" prosecuting attorney Jerry Blackwell asked.
"Asphyxia is a commonly understood term", he noted.
On cross-examination, Langenfeld said that hypoxia can be caused by many things, including drugs such as fentanyl, methamphetamine or a combination of both.
Pain, trauma and regret spilled out from the Minneapolis courtroom last week as a series of bystanders and first-responders spoke about watching Floyd's last breaths.
The disturbing recording of Floyd being pinned down by Chauvin for almost nine minutes and saying "I can't breathe" has been widely circulated on social media and in news reports, and has ignited mass protests against police brutality and systemic racism.
Blackwell said Chauvin knelt for 4 minutes and 45 seconds as Floyd cried out for help, 53 seconds as he flailed due to seizures, and 3 minutes and 51 seconds as Floyd was non-responsive.
They heard from the nine-year-old, "sad and mad" by what she had seen May 25, 2020 when she went to Cup Foods to buy snacks and candy with her cousin, Darnella Frazier, the 17-year-old bystander who lifted up her cell phone and recorded the video that went viral.
'I don't feel that viewing and discussing this case in school is age-appropriate for scholars, ' Miller was said to have written in a note to families.
"I was sad and kind of mad", the girl testified.
"I didn't have any reason to believe that that was the case here", Langenfeld said.
