Dr. Tobin: the toe of Chauvin's boot is lifted off of the ground so that means that half of Chauvin's body weight plus half of his gear weight - for a total of 91.5 pounds - is coming down directly onto George Floyd's neck.

This is being depicted in Exhibit 943 and it is a compelling exhibit.

Dr. Tobin: the first 5 minutes and 3 seconds of Floyd on the ground: his oxygen levels were enough to keep his brain alive b/c he continued to speak and he was able to verbalize words.

Chauvin's counsel objected & asked for a sidebar after this testimony.

That testimony stands.

Court is taking its 20-minute morning break now.
