The cynic in me says they kept her in jail for five days to try to find something to charge her with for CYA. Hope I’m wrong.
Don’t know, but the way it’s supposed to work is that you sit in jail until a court appearance which is usually the next business day after the arrest or you post bail. If the warrant is an out of state warrant then you sit until you post bail, the out of state agency says fuggetaboutit, or comes and gets you or you get a hearing in front of a judge who releases you for some reason.
