One of the first witnesses called by Derek Chauvin's defense Tuesday testified that he felt the former officer's actions in the arrest of George Floyd were "justified".
Chauvin, 45, is charged with second and third-degree murder and manslaughter in the death of Floyd.
The defense's first witnesses testified about a May 6, 2019, incident in which Floyd was pulled from a vehicle and arrested by Minneapolis police.
The defense called a use of force expert, who said based on his assessment, Chauvin acted accordingly given the circumstances.
"So in this situation, there is space limitations".
Mr Chauvin's lawyer suggested Tuesday that George Floyd may have suffered from "excited delirium", or what a witness described as a potentially lethal state of agitation and even superhuman strength that can be triggered by drug use. There was traffic still driving down the street. "So I think those were relatively valid reasons to keep him in the prone".
Also taking the stand for the defense was Floyd's friend Shawanda Hill and retired paramedic Michelle Monseng.
On cross-examination, prosecutor Erin Eldridge got Moseng to testify that Floyd's respiratory output, pulse, heart rate, EKG and heart rhythms were normal. And medical experts called by prosecutors have testified that Mr Floyd died from a lack of oxygen because of the way he was restrained. Please, please, don't shoot me. "Just tell me what I did'".
Also testifying was Minneapolis Park Police Officer Peter Chang, who helped at the scene that day.
"Did that cause you any concern?" Gannon has said he believed Potter grabbed her gun by mistake while reaching for her taser.
