Just how long can the police hold you without charging you? Arrestees cannot be held without charges for an unreasonable amount of time but that time period differs between states.
On TV shows about the law, the camera shows the arrest and then the accused being told what he's charged with, but it doesn't often show the process in between.
Police can't bring charges against a suspect. Only a prosecutor has the ability to charge a person with a crime.
It may take some time after an arrest before charges are made. But how long can they hold you before there is a violation of your rights?
