From what I could tell he did resist arrest.
They put him in the car on the curb side of the police car. Best I could tell, it looked like he resisted. (another police car was blocking the view ) A cop goes to the other side of the car, opens the door, Floyd's feet start kicking out, he comes out the other door, ends up on the street side of the car and on the street.
I"m no cop, but if I had trouble putting a guy in the car and he ends up coming out the other side kicking, it might qualify as resisting.
