After you are arrested for a crime in Las Vegas, the police will take you to the station for booking and an initial court appearance. From there, you will typically be released if you can give the court an amount of money that is established for “posting bail”. In essence, you are giving the court money and promising that you will show up to all of your future court hearings. As a result, you will be free to leave the jail. The more serious the crime, the higher the bail. If the crime is very serious, the judge may not grant bail at all because the suspect is considered a “flight risk”. In this case, the suspect may be kept in custody throughout the duration of the trial.
