I spent a night in central booking for arson (charges were latter dropped). I got the impression at any given time the people in there are 60% DUI, 30% domestic abuse, 10% everything else. I didn't see anyone being "fucked with". That part must come after indictment if you aren't simply released and given a court date. How big of a difference is it between central and rikers?
