You know I'll still go on my Orange is scum rant even though Retal is an awful cop.
First off, he was the one chasing down Louis the most (who we're assuming was the miller). But then conveniently jumped onto the FRAYDO train, which FRAYDO called him out on really hard.
And I'll even mentioned that FRAYDO suspected me of being scum, but surprisingly he didn't target me for the Oracle ability. I'd say by that fact he didn't means he was actually hiding his actual thoughts and that's why he also said Orange was leaning town. He was doing double-speak, his real scum suspect was Orange, but he was trying to figure out who the team was, so he targeted someone he didn't talk about much and was unsure of, KY.
And then we have Retal who gave both a scum and town read on Orange. I'm going with him saying the town read to throw the scum team off the trail. So if anything we should trust the cop on a scum read at least.
