No idea if it's the same guy, but he did admit to wearing what appears to be the same sweatshirt on his testimony today.

Strangely enough all of the live feeds died while he was on the stand.

Also, yea his explanation of types of chokes was pretty bad. He switched his own terminology a few times.

Also, I didn't know Chauvin was only 140 pounds... Really doubting that Floyd was passed out from a knee to neck "blood choke" as I can't imagine someone applying ~70 lbs pressure to one artery plus pressure on the other side from the street? would be enough.
