I can say what I would expect, and that is if I saw a cop plant evidence in front of me, I’d turn him in.
Are you a cop? If not, he'd probably turn you in.
I would also be very sad to learn that the planting of evidence is so routine that one cop would do it right in front of another without expecting any trouble from doing so at all.
I suspect that it is. Cops don't rat on one another.
No, I am not, and I bet he would too.
I have heard about the Blue Code too, but if I was a cop and saw another cop framing a man who he just shot to death, he would get ratted on.
That would probably not make me to popular, but I would rather be unpopular than a party to that.
