After burglarizing a house, Tom is caught by the police. Upon apprehension, the police arrest Tom and take him to the local jail. Tom waits in jail until the next morning when he is taken to court for arraignment. During the arraignment, Tom is told of the charges filed against him. At this time, Tom's attorney also asks the court for bail. Because Tom has an extensive prior record, no job, and no family living in the area the judge denies bail and rules that Tom must wait in jail until sentencing. Before the case goes to trial Tom is offered a plea bargain by the district attorney assigned to the case. Complying with the terms of the plea bargain, Tom pleads guilty and is sentenced to 9 months in jail followed by 12 months probation. In the above scenario, the criminal justice process began for Tom when.
