Yes in Oregon it definitly does. Most will never say a word, as they know at that point you have undergone a thorough background check and most likely not one of the BA;s. Most officers are decent about it. It is usually towns like Portland or Eugene that you can have the wyatt earps, but most are not going to cause you any greif. There are exceptions everywhere, but not the majority.
Is there some kind of evidence? Don't get me wrong, I'm not saying that's false info, just hoping to get more certainty of it than someone from an online forum saying "Yep, that's the case."
