You are completely off base there - I am about as far from being of the opinion that all cops are saints as it is possible to be while not actively plotting against them.
Yes, dirty cops. From the movie “Knock Around Guys”....
“We are having trouble with a cop!”
“Yeah... a CORRUPT cop.”
“He said cop.”
i.e. “corrupt” as a modifier to “cop” was unnecessarily redundant.
I remember when people (i.e. stupid people) were saying that the blood from O.J. at the crime scene could have been planted. I was wondering how likely it was that the cops on scene had a vial of O.J.’s blood available to splatter around.
The specifics of this case are immaterial. You said it was easy for a cop to plant DNA evidence - I am still not seeing it.
That being said - I am all for “chain of custody” documentation such that the Police have almost no access AT ALL to any blood or otherwise biological samples of suspects.
Last thing we need is them having some “throwdown” DNA.
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.
