Who should be contacted if an officer is needed for court after a considerable amount of time worked?

The correct choice is to contact the attorney on the case when an officer is needed for court after a considerable amount of time has been worked. This is because the attorney is responsible for coordinating all aspects of the legal proceedings, including the necessity of witness testimony and the availability of officers involved in the case. The attorney will be directly engaged in managing court schedules and will know when and if the officer's presence is required for the case's progression.

In contrast, contacting the arresting officer or the immediate supervisor may not yield the best results for confirming court attendance since they might not have the complete information regarding scheduling or court requirements. The district attorney's role is more about prosecuting the case rather than specifically managing officers' availability for court appearances. Hence, reaching out to the attorney on the case ensures that the proper legal channels are followed and that the officer's presence is confirmed directly by the party responsible for the case.
