A person taken into custody on a material witness warrant is not sent through booking, nor do they have a bail hearing, not unless they are also being charged with a crime. In this instance the wife is just being held as a witness, she is not being charged with a crime. When someone is taken into custody as a witness it is done for their own protection, they are not held in a jail cell, they are put up in a motel room with a police escort. ADA Carver threatening the wife with not receiving bail and going to Riker's Island makes no sense at all.
