I think what the people were saying about the OJ blood is he gave a sample. The police booked it as a certain amount. Then later about half of it was missing. So they had an old retired technician on oxygen say in a video deposition that in all his years of taking blood samples he’d never made a mistake but he must have made a mistake this one time and wrote down more blood than he’d actually taken. I don’t know if the old man made a mistake for the first time in his life or not. But the jurors didn’t buy it.
So you think that sometime after the crime, sometime after the crime scene evidence was collected - OJ gave a blood sample - and then half of that was used to contaminate the crime scene and the crime scene evidence?
The contemporaneous cut on OJ’s hand was purely coincidental no doubt.
The OJ jury was infamously idiotic, partisan, and ignorant. Nice to know you keep good company.
