This game is awesome on how much you can fuck around and found out (a.k.a FAFO).
I'm currently on my 2nd playthrough playing as Nun build with Exhibitionism fetish, and I found out that public urination and public scat is not the only way you can get imprisoned.
Being naked and talking to both moving and standing NPCs (shop NPC being the exception) around the square can get you arrested and imprisoned.
