Transcript for Defense mounts its case in Derek Chauvin trial
We have the latest now on the Derek chauvin murder trial. The defense calling its first witnesses arguing the former police officer's actions were justified. Alex Perez is outside the courthouse in Minneapolis. Good morning, Alex. Reporter: Hey, good morning, robin. Short of a whirlwind of witnesses the defense calling six as they try to convince the jury what Derek chauvin did was appropriate. Call your first witness. For the first time jurors hearing from someone defending Derek chauvin's actions, use of force expert Barry brodd testifying that he was justified and pinning Floyd by the neck was not use of force. Why is it not a use of force? Because that's a control technique. Without it -- it doesn't hurt. Reporter: But on cross-examination the prosecution pushing getting brodd to backtrack. If this act we're looking at here in exhibit 17 could produce pain, would you agree that what we're seeing here is a use of force? Shown in this picture that could be a use of force. Reporter: The prosecutor picking apart his testimony and the notion that Floyd was not complying. What part of this is not compliant? So I see his arm position in the picture that's posted. Right. That, you know, a compliant person would have both their hands in the small of their back and just be resting comfortably versus like he's still moving around. So attempting to breathe while restrained is being slightly noncompliant? No. Reporter: The defense calling six witnesses and arguing it was drug use before the encounter with police and medical problems that killed Floyd. Hill was in his vehicle and told jurors he fell asleep in the parked car and struggled to wake him up when officers arrived. The police is here. The $20 bill wasn't real. I kept saying, baby, get up. When he seen the man, the man had the gun at the window when we looked back to him so he instantly grabbed the wheel and he was like, please, please, don't kill me. Please, don't shoot me. Reporter: And we expect the defense will soon call their own medical experts to testify, robin. All right, Alex, thank you. We are covering the latest on the trial.
