When a person gets arrested in the United States, they likely will be charged with a crime and have a court date set in which they have to attend. If it is not a serious crime, they likely will be released on their own recognizance, but a great deal of the time they will require that you post a bail amount, which is a certain amount of money that is determined by the court, based on the degree of your crimes, which you must pay in order to get out of jail. This also comes with the agreement that you will show up for your court date.
