I had no issues with the cop either. Lots of bent cops throwing their authority around.
The cop's wife on the other hand ......
The plot fell deeper and deeper into being a childish fantasy with each update.
For me personally Radiant should have been about loss and reconnecting with your past and the daughters you never knew you had.
That's why for me the cop felt out of place.
He is unnecessary drama in a story that has enough of that already.
Memory loss, dreams of the girl you had a one night stand with, dealing with her death and the daughters you never knew you had.
Maybe falling in love with them, depends on the route though, and dealing with that.
I think Radiant could have been one of the really good games, but the devs got greedy and squandered all of that.
