This has nothing to do with the police at all. It's all about an s&m club. The bit about Osaka jail is probably a dungeon reference.

What's not to understand about the ending? Getting spanked by a mistress leaves very telling marks that's hard to explain to a partner, hence one bad deed deserves another (the punishment for unfaithfulness).

The dialog in the beginning sounds really familiar. I'm sure it's taken from a movie. Ichi the Killer mabye. I think I'll have to go throuhg my film collection to find it now.
