Tateo wants to get arrested and be served justice? I'm suspicious, he went out of his way to enjoy life and be as covert as possible before this. He's got to have something else up his sleeves.
Osaragi agrees with this suspicion, but hey, he has a chance to catch the main distributor of Jumbo Max with Fukuchi. You can't look at gift horse in the mouth. Kawakubo has a few ideas, but he can't quite piece things together either. So he goes forward with this plan.
