I've actually been stopped by uniformed officers minutes after spotting the absolute most obvious undercover cop in the world in Ohio.
My crime? I said "Good Morning OFFICER!" really loud as I passed him at the park. There were a lot of people walking around for an art festival and supposedly the local PD got a "tip" it was being used to hide "illegal liberal activities"
Dude was wearing preshly pressed clothing that looks like he literally bought it from Abercrombie that morning. Basically the whole outfit says "I am trying to fit in, this is what we see you people as, look at how hip and cool I am fellow kids" and the haircut was so out of place I literally did a double take.
COPS don't know how to not be cops, even when they're trying their hardest to pretend so they can catch people doing mysterious and vague criminal things.
