Police Officer and a Hypothetical scenario  

I want to run this by you lotters and see what you think about this. A police Officer finds a pill in his car. He doesn't know what it is or where it came from. So he seeks out an answer to the identification of this pill. OK. Now it more than likely came from someone he had transported.He isn't going to be interrogated nor will any legal issues arise for this officer. Now lets think about this from the opposite side of the fence so to speak. Someone (non-law enforcement) gets pulled over. The officer notices a pill on the floor of the car. He questions the person about the discovery. The person replies that they do not know what it is or how it got there. Right? just for the sake of this argument lets say that they really do not know. Do you think the officer is going to believe them? Or give them the benefit of the doubt? You think this person will suffer no consequences and go on with their day? Is it fair that someone can suffer from the actions of someone else? Would love to know what you think.
