Think of it this way, the diner is filled with interesting characters and some of them are actually wanted individuals. The cops say:
"Hey- they're all cooped up in one spot ready to be arrested, so why not arrest them all together?"
Razzy and Droplet are innocent unless they open their mouth about their life style and how they rob the houses.
Katerina and Logan on the other hand- are people on the run since Katerina killed the Russian president and Logan is an escapee from a concentration camp for the unworthy people.
Vyse- has nothing to do with the two parties, rendering him completely innocent- unless he joins the fray.
That should be simple to understand.
