I went back to check and there are two masks in play here - but only two masks that I can see.
1) Chauvin is wearing a mask at points ... but not all. After they take Floyd out of the car and walk him across the street he is wearing a mask; however, seconds before, when he’s speaking with woman at the wall, it appears you can see his mouth. The partner is NOT wearing a mask.
2) The “Park Police” officer is wearing a cloth mask in the “restaurant surveillance” footage.
HOWEVER seemingly nobody else - none of the pedestrians - & the “park police” body cam footage is a total fraud so everything in these pictures is suspect & produced IMO.
Picking a nit... Ambulance guys are wearing masks...
