shanna, dr. tobin, this veteran lung doctor, earlier today testified that george floyd's death was caused largely by derek chauvin's knees pressing against his neck and back making it impossible for him to breathe and that mr. floyd showed signs of a brain injury about four minutes before derek chauvin actually lifted his knee from his neck. has the defense been able to undermine that testimony on cross? there was that point where tobin sort of laughed and said you're trying to confuse me, said it in jest. they're trying to make everything with certitude appeared to the jury that it's perhaps unknowable. >> i thought they were trying to cut into the testimony in key places where they thought they could get wins. this particular expert was very engaging and very clear and he actually took command of his own testimony, which you don't see often with these types of witnesses. nelson's ability to cut into this testimony wasn't as vong as i would have expected. this particular expert kept control of h

shanna lloyd is a civil rights attorney and joins me now. shanna, i found the testimony today as powerful as any i've seen partly because it just reacquainted us with one of the most awful spectacles any of us have witnessed recently. from a legal perspective, did you find it effective? >> i found it wildly effective. i think this was an expert who did something that most expert witnesses have trouble doing, which is connecting with the jury. he engaged them. they were following his every word. and he clarified what everyone's been watching this video to see. when was the moment that george floyd might have passed? he identified it and was definitive about it and that's going to be a moment that sticks with this jury when they go into deliberation. >> i feel like there's an arc here, not even talking about the jury, but public understanding, because we all saw the video, which is to see the video and say, oh, my god, he snuffed that man's life out. and then there was a kind of counternarrative that got spun up by people, apoll gists particul

. >> so after everything the jury's heard, shanna, what's the significance of this?ance is the defense got the acknowledgement that a crowd can interfere with their ability to render medical aid. it can cause them to have to pay attention to the crowd versus being able to do what they would normally do when it comes to medical aid. so the defense did get that nugget out of that particular witness. >> i want to ask you. there have been some witnesses who have said, yes, you can use a knee on a suspect, but not on their neck. perhaps their shoulder blades or maybe their neck if necessary. here is the graphic, i believe, of a police training video where you see what looks like a knee to the middle of the shoulder blades of a suspect. do you think the testimony or this photograph in some way exonerate chauvin with what he did? >> i don't think it exonerated chauvin. i do think they had a better day yesterday than previous days. let's talk about the shoulder. it does show a photo of an officer with his knee between the shoulder blades, but more importantly, floyd was hand
